Judgments of frequency and recency: How they relate to reports of subjective awareness.

In 2 experiments, the author explored the relations of remember versus familiar ratings to judgments of frequency (JOFs) and to judgments of recency (JORs). In both cases, remembered items were associated with more accurate memory judgments. In general, familiar items were judged to have occurred less frequently and less recently than remembered items. However, JOFs and JORs associated with familiar items were more accurate than chance. Implications for theories of remember versus familiar ratings, JOFs, and JORs are considered. Some basic findings that constrain these theories are that (a) remember versus familiar ratings were less sensitive than JOF to presentation frequency and less sensitive than JOR to recency and (b) although remember versus familiar ratings are strongly related to both JOF and JOR, as measured by gamma, the relations are far from perfect.

Subjective qualities of memories associated with the picture superiority effect in schizophrenia.

Patients with schizophrenia (n=24) matched with 24 normal subjects were presented with both words and pictures. On a recognition memory task, they were asked to give remember, know, or guess responses to items that were recognized on the basis of conscious recollection, familiarity, or guessing, respectively. Compared with normal subjects, patients exhibited a lower picture superiority effect selectively related to remember responses. Unlike normal subjects, they did not exhibit any word superiority effect in relation to guess responses; this explains why the overall picture superiority effect appeared to be intact. These results emphasize the need to take into account the subjective states of awareness when analyzing memory impairments in schizophrenia.

Consciousness, control, and confidence: The 3 Cs of recognition memory.

The contributions of recollection and familiarity to recognition memory performance were examined using the process dissociation, remember–know, and receiver operating characteristic (ROC) procedures. Under standard test conditions the 3 measurement procedures led to process estimates that were almost identical and to similar conclusions regarding the effects of different encoding manipulations. Dividing attention led to a large decrease in recollection and a smaller, sometimes nonsignificant, decrease in familiarity. Semantic compared with perceptual processing led to a large increase in recollection and a moderate increase in familiarity. Moreover, the results showed that familiarity was well described by classical signal-detection theory but that recollection reflected a threshold process. The convergence observed across the 3 measurement procedures shows that the 3 procedures tap similar underlying processes and that recollection and familiarity differ in terms of conscious awareness, intentional control, and the manner in which they contribute to the shape of response confidence ROCs.

Reinforcer probability, reinforcer magnitude, and the reinforcement context for remembering.

Traditional theories of delayed matching-to-sample performance do not predict that accuracy will improve when absolute levels of reinforcement are increased. This prediction emerges only when reinforcement context is considered (J. A. Nevin, M. Davison, A. L. Odum, & T. A. Shahan, 2007). To provide quantitative data, the authors factorially manipulated between conditions the probability and duration of reinforcement for correct choices by pigeons. In Experiment 1, increasing the value of either variable improved initial discriminability of the forgetting functions, but did not affect the rate of forgetting. In Experiment 2, initial discriminability covaried with changes in choice immediacy and trial completion rate, suggesting a relationship with response strength consistent with Nevin et al.’s behavioral momentum model. Adding reinforcement context to K. G. White and J. T. Wixted’s (1999) model also generates predictions consistent with the present experiments and with the effects of manipulating extraneous reinforcement. The inclusion of reinforcement context thus improves predictions of delayed matching-to-sample performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Everyday memory compensation: The impact of cognitive reserve, subjective memory, and stress.

To determine the potential importance of several unexplored covariates of everyday memory compensation, the authors examined relations between responses on the Memory Compensation Questionnaire (a self-report measure of everyday memory compensation) and cognitive reserve (education and verbal IQ), subjective memory, and life stress in 66 older adults (mean age = 70.55 years). Key results indicated that compensation occurred in people (a) whose IQ level was greater than their education level (representing cognitive reserve “discordance”) but not in people whose IQ was commensurate with their education (representing cognitive reserve “concordance”); (b) who had greater perceived memory errors; and (c) who experienced heightened stress. Further, high-stress older adults compensated whether perceived memory errors were low or high, but low-stress older adults compensated only if they perceived high memory errors. Bootstrapped confidence intervals around model betas provided further support for estimate reliability. These results suggest boundary conditions for the concept of cognitive reserve, and highlight the importance of subjective memory and life stress for defining contexts in which compensation may occur.

Influence of Emotion on Memory for Temporal Information.

Contextual information, such as color and spatial location, has been found to be better remembered for emotional than for neutral items. The current study examined whether the influence of emotion extends to memory for another fundamental feature of episodic memory: temporal information. Results from a list-discrimination paradigm showed that (a) item memory was enhanced for both negative and positive pictures compared with neutral ones and was better for negative than for positive pictures and (b) temporal information was better remembered for negative than for positive and neutral pictures, whereas positive and neutral pictures did not differ from each other. These findings are discussed in relation to the processes involved in memory for temporal information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotion processing in the criminal psychopath: The role of attention in emotion-facilitated memory.

The response modulation hypothesis specifies that low-anxious psychopathic individuals have difficulty processing information outside their primary attentional focus. To evaluate the applicability of this model to affective processing, the authors had 239 offenders, classified with the Psychopathy Checklist--Revised (R. D. Hare, 2003) and the Welsh Anxiety Scale (G. Welsh, 1956), perform 1 of 3 emotion memory tasks that examined the effects of emotion on memory for primary and contextual information. Regardless of anxiety level, psychopathic and control offenders demonstrated a significant and comparable memory bias for emotional over neutral words in the primary conditions. However, psychopathic individuals showed significantly less memory bias than did controls in the contextual conditions. Results indicate that the impact of emotion on memory is moderated by attentional factors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

False memories in children and adults: Age, distinctiveness, and subjective experience.

This study investigated developmental trends associated with the Deese/Roediger-McDermott false-memory effect, the role of distinctive information in false-memory formation, and participants' subjective experience of true and false memories. Children (5- and 7-year-olds) and adults studied lists of semantically associated words. Half of the participants studied words alone, and half studied words accompanied by pictures. There were significant age differences in recall (5-year-olds evinced more false memories than did adults) but not in recognition of critical lures. Distinctive information reduced false memory for all age groups. Younger children provided with distinctive information, and older children and adults regardless of whether they viewed distinctive information, expressed higher levels of confidence in true than in false memories. Source attributions did not significantly differ between true and false memories. Implications for theories of false memory and memory development are discussed.

Regulation of memory accuracy with multiple answers: The plurality option.

We report two experiments that investigated the regulation of memory accuracy with a new regulatory mechanism: the plurality option. This mechanism is closely related to the grain-size option but involves control over the number of alternatives contained in an answer rather than the quantitative boundaries of a single answer. Participants were presented with a slideshow depicting a robbery (Experiment 1) or a murder (Experiment 2), and their memory was tested with five-alternative multiple-choice questions. For each question, participants were asked to generate two answers: a single answer consisting of one alternative and a plural answer consisting of the single answer and two other alternatives. Each answer was rated for confidence (Experiment 1) or for the likelihood of being correct (Experiment 2), and one of the answers was selected for reporting. Results showed that participants used the plurality option to regulate accuracy, selecting single answers when their accuracy and confidence were high, but opting for plural answers when they were low. Although accuracy was higher for selected plural than for selected single answers, the opposite pattern was evident for confidence or likelihood ratings. This dissociation between confidence and accuracy for selected answers was the result of marked overconfidence in single answers coupled with underconfidence in plural answers. We hypothesize that these results can be attributed to overly dichotomous metacognitive beliefs about personal knowledge states that cause subjective confidence to be extreme.

The length of the retention interval, forgetting, and subjective similarity.

A long retention interval tends to result in the poor retention known as forgetting. A high subjective similarity between stimuli frequently produces their poor retention. Thus, a long retention interval may increase the subjective similarity between stimuli (the RIISS hypothesis), and this increase may produce forgetting. To examine this hypothesis, college students made speeded same-different discriminations between two lines or tones of different lengths or frequencies that were 400 ms or 3,300 ms apart, and they rated the similarity of these stimuli. The long interval produced poorer overall performance as expected, but also produced poorer performance on different than same stimuli, implying that it increased the subjective similarity between the initial and subsequent stimuli, and it also increased rated similarity, in support of the RIISS hypothesis. The position that stored stimuli lose less common information than distinctive information explains RIISS evidence better than does perturbation theory.

A sociocultural stress, appraisal, and coping model of subjective burden and family attitudes toward patients with schizophrenia.

A sociocultural stress, appraisal, and coping model was developed to understand relatives' burden of care and negative affective attitudes toward patients with schizophrenia. Ninety-two African American and 79 White patients and a significant other (80% mothers) completed 2 10-min family problem-solving discussions. In addition, the Kreisman Rejection Scale and a global self-report rating of family burden were administered to relatives, and a self-report rating of substance use was administered to patients. Results indicated that subjective burden of care and patients' odd and unusual thinking during the family discussion each independently predicted relatives' attitudes toward patients, suggesting that negative attitudes are based in part on both patients' symptoms and perceived burden of care. African American relatives' perceived burden was also predicted by patients' substance abuse. Finally, White family members were significantly more likely than African Americans to feel burdened by and have rejecting attitudes toward their schizophrenic relative suggesting that cultural factors play an important role in determining both perceived burden and relatives' attitudes toward patients.

Social class, sense of control, and social explanation.

Lower social class is associated with diminished resources and perceived subordinate rank. On the basis of this analysis, the authors predicted that social class would be closely associated with a reduced sense of personal control and that this association would explain why lower class individuals favor contextual over dispositional explanations of social events. Across 4 studies, lower social class individuals, as measured by subjective socioeconomic status (SES), endorsed contextual explanations of economic trends, broad social outcomes, and emotion. Across studies, the sense of control mediated the relation between subjective SES and contextual explanations, and this association was independent of objective SES, ethnicity, political ideology, and self-serving biases. Finally, experimentally inducing a higher sense of control attenuated the tendency for lower subjective SES individuals to make more contextual explanations (Study 4). Implications for future research on social class as well as theoretical distinctions between objective SES and subjective SES are discussed.

Spatial exploration is required for the formation of contextual fear memory.

The acquisition of contextual fear in mice is thought to require the formation of a conjunctive representation of the conditioning chamber. This can be achieved during a minimum of 20 to 40 s of exploration immediately prior to the shock or during preexposure to the context at an earlier time. An animal receiving less time in the chamber will show reduced freezing 24 hr later, a condition termed the immediate shock deficit (ISD). In this study, the authors have attempted to uncouple the formation of a contextual representation, based on the conjunction of a defined set of cues, from the establishment of a spatial representation, which requires active exploration, by inserting a transparent plastic partition in the center of the chamber. Taking advantage of the ISD and the context preexposure effect, the authors found that animals preexposed to one side of the chamber on Day 1, but shocked on the other side on Day 2, show significantly less fear than animals exposed to and shocked on the same side. Our results indicate that spatial exploration is necessary for mice to benefit from contextual preexposure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What Do We Know About What We Cannot Remember? Accessing the Semantic Attributes of Words That Cannot Be Recalled.

Two experiments examined access to the semantic attributes of words that participants failed to retrieve. The results indicated access to all 3 dimensions of the semantic differential--evaluation, potency, and activity, as revealed by attribute judgments and by the nature of the commission errors made. There was no evidence for superior access to the emotional-evaluative dimension, inconsistent with what may be expected from the claimed primacy of emotion. In comparison with complete recall, partial recall exhibited a slower rate of forgetting and a stronger tendency to elicit know rather than remember responses. The results were discussed in terms of the processes that lead to partial recall and in terms of the possibility that the affective primacy hypothesis does not apply to memory retrieval.

It feels like yesterday: Self-esteem, valence of personal past experiences, and judgments of subjective distance.

Supporting predictions from temporal self-appraisal theory, participants in 3 studies reported feeling farther from former selves and experiences with unfavorable implications for their current self-view than from equally distant selves and experiences with flattering implications. This distancing bias occurred when assignment to negative and positive pasts was random, for both achievement and social outcomes and for single episodes as well as longer term experiences. Consistent with a motivational interpretation, the distancing bias was stronger among high than low self-esteem participants and occurred for personal but not for acquaintances' past events. Frequency of rehearsal and ease of recall of past episodes also predicted feelings of distance, but these variables did not account for the Self-Esteem × Valence interaction on subjective distancing of personal events.

Surprise, memory, and retrospective judgment making: Testing cognitive reconstruction theories of the hindsight bias effect.

Hindsight bias has been shown to be a pervasive and potentially harmful decision-making bias. A review of 4 competing cognitive reconstruction theories of hindsight bias revealed conflicting predictions about the role and effect of expectation or surprise in retrospective judgment formation. Two experiments tested these predictions examining the effects of manipulating the information presented in a text-based scenario and its congruency with the given outcome on surprise, hindsight bias, and recall. The results of Experiment 1 revealed evidence of hindsight bias after exposure to incongruent and ambivalent outcomes but not after exposure to congruent outcomes. Experiment 2 replicated the hindsight bias results and found that the ratio of outcome consistent information recalled was higher than expected in the incongruent and ambivalent conditions but equaled the ratio presented to participants in the congruent condition. The results were interpreted as supporting the general predictions of sense-making models of the hindsight bias. A refined version of this model is discussed.

Goal adjustment capacities, coping, and subjective well-being: The sample case of caregiving for a family member with mental illness.

This study examined the associations between goal adjustment capacities, coping, and indicators of subjective well-being in 2 waves of data from individuals who provide care for a family member with mental illness. We hypothesized that goal adjustment capacities would predict higher levels of subjective well-being by facilitating coping with caregiving stress. Results showed that goal disengagement was associated with effective care-specific coping (e.g., less self-blame and substance use). Goal reengagement was also associated with effective care-specific coping (e.g., positive reframing), but at the same time it predicted the use of less effective strategies (e.g., venting and self-distraction). Moreover, goal disengagement predicted lower levels of caregiver burden and depressive symptoms and buffered the longitudinal effect of caregiver burden on increases in depressive symptoms. Goal reengagement, by contrast, predicted higher levels of caregiver burden and purpose in life and buffered the cross-sectional association between caregiver burden and depressive symptoms. Finally, effective (and less useful) care-specific coping statistically explained the adaptive (and maladaptive) effects of goal adjustment capacities on participants' well-being.

Social Exclusion and the Deconstructed State: Time Perception, Meaninglessness, Lethargy, Lack of Emotion, and Self-Awareness.

The authors hypothesize that socially excluded individuals enter a defensive state of cognitive deconstruction that avoids meaningful thought, emotion, and self-awareness, and is characterized by lethargy and altered time flow. Social rejection led to an overestimation of time intervals, a focus on the present rather than the future, and a failure to delay gratification (Experiment 1). Rejected participants were more likely to agree that "Life is meaningless" (Experiment 2). Excluded participants wrote fewer words and displayed slower reaction times (Experiments 3 and 4). They chose fewer emotion words in an implicit emotion task (Experiment 5), replicating the lack of emotion on explicit measures (Experiments 1-3 and 6). Excluded participants also tried to escape from self-awareness by facing away from a mirror (Experiment 6). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

When subjective experiences matter: Power increases reliance on the ease of retrieval.

Past research on power focused exclusively on declarative knowledge and neglected the role of subjective experiences. Five studies tested the hypothesis that power increases reliance on the experienced ease or difficulty that accompanies thought generation. Across a variety of targets, such as attitudes, leisure-time satisfaction, and stereotyping, and with different operationalizations of power, including priming, trait dominance, and actual power in managerial contexts, power consistently increased reliance on the ease of retrieval. These effects remained 1 week later and were not mediated by mood, quality of the retrieved information, or number of counterarguments. These findings indicate that powerful individuals construe their judgments on the basis of momentary subjective experiences and do not necessarily rely on core attitudes or prior knowledge, such as stereotypes.

Review of Three men: An experiment in the biography of emotion.

Reviews the book, Three men: An experiment in the biography of emotion by Jean Evans (1954). The unusual quality of Evans' writing lies in the happy blend she has achieved of the good qualities of both artist and scientist. The first two "portraits" in this book are of men at least a significant portion of whose lives was lived under conditions of real poverty. In the case of the third man, however, this was not the case. "Martin Beardson's" father was a prosperous business man, his mother an "upper class" woman of "genteel tradition." "Except for brief periods, and then only in recent years, Martin has never known deprivation in terms of food, clothing, and comfortable shelter. By realistic standards he also enjoyed many luxuries . . . . Yet Martin has always had a sense of poverty no less poignant than if he had been a slum child, and a sense of grievance no less biting than if he had lived all his life on the periphery of want" (p. 195). This is a book that will be read with pleasure and pondered with profit by many scientists and professionals in clinical, social, and dynamic psychology, in sociology, psychotherapy, social work, and a number of other related fields.
