Aging, episodic memory feeling-of-knowing, and frontal functioning.

Groups of normal old and young adults made episodic memory feeling-of-knowing (FOK) judgments and took 2 types of episodic memory tests (cued recall and recognition). Neuropsychological tests of executive and memory functions thought to respectively involve the frontal and medial temporal structures were also administered. Age differences were observed on the episodic memory measures and on all neuropsychological tests. Compared with young adults, older adults performed at chance level on FOK accuracy judgments. Partial correlations indicated that a composite measure of frontal functioning and FOK accuracy were closely related. Hierarchical regression analyses showed that the composite frontal functioning score accounted for a large proportion of the age-related variance in FOK accuracy. This finding supports the idea that the age-related decline in episodic memory FOK accuracy is mainly the result of executive or frontal limitations associated with aging.

Context affects feeling-of-knowing accuracy in younger and older adults.

In feeling of knowing (FOK) studies, participants predict subsequent recognition memory performance on items that were initially encoded but that cannot presently be recalled. Research suggests that FOK judgment magnitude may be influenced by the total amount, or quantity, of contextual information retrieved related to the unrecalled target (e.g., Koriat, 1993). The present study examined the contribution of quality of that information to episodic FOK judgments. In addition, we tested whether the episodic FOK deficit demonstrated by older adults could be reduced by encouraging retrieval of contextual information relevant to the target. Three experiments demonstrated that quality of the retrieved partial information influenced FOK judgments in both older and younger adults; however, the manifestation of that influence was age dependent. The results also indicated that older adults required explicit retrieval of contextual information before making FOK judgments in order to make accurate FOK predictions. The results suggest that FOK accuracy may be partially determined by search processes triggered when participants are queried for contextual information.

Memory and metamemory: A study of the feeling-of-knowing phenomenon in amnesic patients.

Tested accuracy of the feeling of knowing in 2 experiments, using 8 patients with Korsakoff's syndrome (mean age 54 yrs), 8 electroconvulsive shock therapy (ECT) patients (mean age 46.5 yrs), 4 Ss (mean age 47 yrs) with other causes of amnesia, 2 alcoholic control groups (7 Ss with a mean age of 47.6 yrs and 19 Ss with a mean age of 48.5 yrs), and 18 healthy controls (mean age 49 yrs). In Exp I, feeling-of-knowing accuracy for the answers to general information questions that could not be recalled was tested. Ss were asked to rank nonrecalled questions in terms of how likely they thought they would be to recognize the answers and were then given a recognition test for these items. Only Korsakoff's syndrome Ss were impaired in making feeling-of-knowing predictions. The other amnesic Ss were as accurate as control Ss in their feeling-of-knowing predictions. In Exp II, these findings were replicated in a sentence memory paradigm that tested newly learned information. Results show that impaired metamemory is not an obligatory feature of amnesia, because amnesia can occur without detectable metamemory deficits. The impaired metamemory exhibited by patients with Korsakoff's syndrome reflects a cognitive impairment that is not typically observed in other forms of amnesia.

Accuracy of feeling-of-knowing judgments for predicting perceptual identification and relearning.

The feeling of knowing (FOK) refers to predictions about subsequent memory performance on previously nonrecalled items. The present research explored predictive accuracy with 2 new FOK criterion tests (in addition to recognition): relearning and perceptual identification. In 2 experiments, Ss attempted to recall the answers to general information questions, then made FOK predictions for all nonrecalled answers, and finally had a criterion test to assess the accuracy of the FOK predictions. Exp I, conducted with 32 undergraduates, demonstrated that perceptual identification can be employed successfully as a criterion test for the feeling of knowing FOK. This opens a new way for metamemory research via perception. Moreover, the FOK accuracy for predicting perceptual identification was not significantly correlated with the FOK accuracy for predicting recognition, in accord with the idea that these 2 tests assess memory differently. Exp II, conducted with 77 undergraduates, demonstrated that relearning performance can also be predicted by FOK judgments. Overall results show that there is a positive relationship between the FOK and the amount of time elapsing before a memory search is terminated during recall.

A comparison of current measures of the accuracy of feeling-of-knowing predictions.

Discusses 8 quantitative measures of feeling-of-knowing accuracy that have been used in the literature. The 3 measures considered at length are J. T. Hart's (see record 1965-13971-001) difference score, L. A. Goodman and W. H. Kruskal's (1954) gamma correlation, and the phi correlation. Quantitative relations between these measures are reported, as are connections with some basic axioms and a probabilistic conception of feeling-of-knowing accuracy. The currently most popular measure, the Hart difference score, has serious shortcomings. The Goodman-Kruskal gamma seems to be best. The remaining measures are inappropriate for the available feeling-of-knowing data for a variety of reasons. Also discussed are the implications of these results for other situations in which ordered 2?×?2 tables are examined to determine the relationship between predictions and criterion performance.

Cue familiarity but not target retrievability enhances feeling-of-knowing judgments.

Two hypotheses concerning people's ability to predict later memory performance for unrecalled items were investigated. The target retrievability hypothesis states that feeling-of-knowing judgments (FKJs) are based on partial target information, and the cue familiarity hypothesis asserts that they are based on recognition of the cues. In Exps 1 and 2, Ss either generated or read the targets of paired associates. Half of the cues had been primed in a pleasantness-rating task. The generation manipulation increased recall but had no effect on FKJs. Cue priming had no effect on recall but increased FKJs. In Exp 3, using general information questions primed after the initial recall attempt, both cue and target priming increased FKJs. Exp 4, which remedied difficulties in Exp 3, showed no effect of target priming, whereas cue priming increased FKJs. The results favor the cue familiarity hypothesis.

Age differences in feeling-of-knowing and confidence judgments as a function of knowledge domain.

For two semantic knowledge domains, general and computer-related, feeling-of-knowing (FOK) and confidence level (CL) ratings and their relative accuracy were assessed in young, middle-aged, and older adults, after test difficulty was equated across age groups. Global memory self-efficacy beliefs were also assessed for each domain. As expected, greater age was associated with poorer memory self-efficacy beliefs only in the computer domain. The oldest two groups were found to be more underconfident than young adults when rating their FOK but not their CL, for computer items but not for general items. Statistical control of age differences in memory self-efficacy beliefs in the relevant domain greatly reduced this age effect on computer-related FOK ratings. This finding suggests that absolute FOK judgments are more closely related to memory self-efficacy beliefs than are CL judgments. Gamma correlations between judgments and recognition performance revealed that all age groups were equally accurate in FOK and in CL judgments, in both domains.

Attribute dominance in memory development.

72 children, 36 each from the 1st and 6th grades, were given a 70-item study list followed by a recognition test list of equal length. Items were line drawings of common objects accompanied by orally presented verbal labels. To provide an indication of the relative dominance of features encoded at the 2 ages, labels, pictures, and referents were manipulated in various combinations to form visual, semantic, and acoustic distractors, which were included in the test list. Significant numbers of false recognitions (as measured against false-recognition rates for control words) were elicited by visual distractors for both age groups, by acoustic distractors for 1st graders and by semantic distractors for 6th graders and 1st grade females. Implications for hypotheses concerning the role of visual representation and the developmental onset of semantic encoding are discussed.

Attribute conjunctions and the part configuration advantage in object category learning.

Five experiments demonstrated that in object category learning people are particularly sensitive to conjunctions of part shapes and relative locations. Participants learned categories defined by a part's shape and color (part-color conjunctions) or by a part's shape and its location relative to another part (part-location conjunctions). The statistical properties of the categories were identical across these conditions, as were the salience of color and relative location. Participants were better at classifying objects defined by part-location conjunctions than objects defined by part-color conjunctions. Subsequent experiments revealed that this effect was not due to the specific color manipulation or the role of location per se. These results suggest that the shape bias in object categorization is at least partly due to sensitivity to part-location conjunctions and suggest a new processing constraint on category learning.

Age differences in memory retrieval shift: Governed by feeling-of-knowing?

The noun-pair lookup (NP) task was used to evaluate strategic shift from visual scanning to retrieval. We investigated whether age differences in feeling-of-knowing (FOK) account for older adults' delayed retrieval shift. Participants were randomly assigned to one of three conditions: (1) standard NP learning, (2) fast binary FOK judgments, or (3) Choice, where participants had to choose in advance whether to see the look-up table or respond from memory. We found small age differences in FOK magnitudes but major age differences in memory retrieval choices that mirrored retrieval use in the standard NP task. Older adults showed lower resolution in their confidence judgments (CJs) for recognition memory tests on the NP items, and this difference appeared to influence rates of retrieval shift, given that retrieval use was correlated with CJ magnitudes in both age groups. Older adults had particular difficulty with accuracy and confidence for rearranged pairs, relative to intact pairs. Older adults' slowed retrieval shift appears to be attributable to (1) impaired associative learning early in practice, not just a lower FOK; but also (2) retrieval reluctance later in practice after the degree of associative learning would afford memory-based responding.

Automatic memory search and the effects of information load and irrelevant information.

If automaticity is identified with both light capacity usage and little attentional selectivity, then an automatic process should be symptomatized by both small effects of concurrent information load and large susceptibility to interference by similar but irrelevant information. Several experiments are reported that test this prediction for memory search among sets of words. For well-learned memory sets, a small effect of information load co-occurs with a large effect of irrelevant information. By contrast, for arbitrary sets, a large effect of information load co-occurs with a small effect of irrelevant information. These results do confirm the correlation between effects of information load and irrelevant information as a hallmark for identifying automatic processes.

Depression and information processing: Self-schemata and the encoding of self-referent information.

Tested the suggestion made by cognitive theorists that in depression, negative environmental events can activate self-schemata that structure the processing of information in a negative fashion. Either success or failure feedback was provided to 23 depressed and 24 nondepressed female undergraduates (determined by Beck Depression Inventory scores), and the personal favorability of trait adjectives recalled in a depth-of-processing paradigm was examined. At the self-referent processing level, depressed Ss did not respond to success feedback by processing and recalling more favorable self-references, while nondepressed Ss did so respond. These findings suggest that depressed individuals suffer from a deficit in the ability to activate positive self-schemata with which to process positive self-relevant information and not necessarily from an oversensitivity in the processing of negative information.

Knowledge-based information acquisition: Norms and the functions of consensus information.

Mill's (1872/1973) method of difference prescribes that the lay scientist should use consensus information as a control condition for the person and distinctiveness information as a control condition for the stimulus when analyzing their causal effects on the occurrence of the target event. However, in studies of information acquisition, subjects have shown a consistent preference for distinctiveness information when answering causal questions about the person, and for consensus information when answering causal questions about the stimulus. To explain this discrepancy, we distinguish between the evaluative, contrastive, and corroborative functions of consensus and distinctiveness information. In addition, we suggest that Ss seek consensus information only if it is relevant to the question posed to them, and if they cannot supply it from their own presupposed knowledge of behavioral norms. We report 4 information acquisition experiments that provide support for our analysis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attribute criteriality and sex-linked conservatism as determinants of psychological similarity.

"Two hypotheses were proposed: 1… . One event is more likely to be judged similar to a standard event if the two differ on some property which… has not been learned as criterial for defining it, than if this property has been learned as criterial for its definition. 2… . When presented with events of varying criterial difference from a standard, females should judge fewer of these events as similar to the standard than males, on the ground that the former tend to categorize more narrowly… . It was concluded that recognition of similarity depends on learned classification rules and on individual differences in conceptual conservatism."

Eliciting information from groups: Social information and the Concealed Information Test.

Polygraph recordings of physiological reactions to a Group Concealed Information Test identified exposure to one of three mock village scenarios. Sixty-nine participants worked in groups on a card construction project while viewing tea making, bomb making, or no event. Participants denied knowledge of the events, but skin resistance and heart rate scores analysed by means of a multivariate analysis of variance, F(8, 106) = 4.08, and analyses of variance showed the tea group responding most on tea-related questions on skin resistance, F(2, 56) = 11.57, and heart rate, F(2, 56) = 4.58. The bomb group was highest for skin resistance, F(2, 56) = 6.17. Four of five and three of four groups who witnessed bomb and tea making, respectively, were identified at the 90% level of confidence, with combined scores suggesting that populations exposed to dangerous activities can be selectively distinguished.

Multiattribute judgment: Attribute spacing influences single attributes.

The authors examine how the spacing of attribute levels influences single- and multiattribute judgments. Participants rated the overall attractiveness of apartments described by monthly rent, distance to campus, and a friend's opinion. An identical set of apartments was presented in 4 attribute spacing contexts. Distance levels for most apartments were either relatively far from campus or relatively close to campus. Rent levels for most apartments were either relatively expensive or relatively inexpensive. Judged attractiveness of identical apartments varied across contexts; a given attribute difference had a greater effect when it spanned more attribute levels. Moreover, rank orders of the same apartments reversed with changes in context. Results were consistent with the theory that perceptions of attribute levels vary with spacing in a manner consistent with range-frequency theory (A. Parducci, 1995), although response effects may also occur. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Canadian content and the WISC-R information subtest.

In 2 studies, 7 WISC-R Information subtest items were altered as recommended by P. E. Vernon (1977) to make them more appropriate for Canadian children. For 210 normal 4th–10th graders and 52 students (mean age 12 yrs 5 mo) referred for assessment, responses to the modified items were compared to responses to the original manual items. Data were also compared to data from the American standardization group (D. Wechsler, 1974). On the basis of these comparisons, it is suggested that Vernon's changes be adopted.

Self-consciousness and the processing of self-relevant information.

Three experiments were conducted to examine cognitive processes involved in self-conscious behavior. According to Hull and Levy (1979), self-consciousness is associated with processes involved in self-referent encoding. The present studies advance the more specific hypothesis that self-consciousness is involved with the aspect of self-reference associated with the activation of knowledge about the self. Experiment 1 used a self-reference paradigm and found that self-consciousness increased the extent to which a manipulation of accessible self-knowledge influenced self-referent encoding. Experiment 2 used a self-perception paradigm and found that self-consciousness increased the extent to which a manipulation of accessible self-knowledge affected subsequent self-perception. Experiment 3 used a correlational design to demonstrate how cognitive processes associated with self-reference may mediate self-conscious behavior. Individual differences in self-referent encoding were associated with individual differences in self-consciousness; both variables were associated with increased affective reactions to self-relevant feedback; and partialing out individual differences in self-referent encoding eliminated the effects of self-consciousness. These results are discussed in terms of their implications for reconciling various theories of self-consciousness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

On the distinction between artifacts and information.

G. Sperling et al. (see record 1990-06589-001) argued that all previous research on the kinetic depth effect has been contaminated by stimulus artifacts, and they developed a new task that they believe can successfully overcome this problem. The present discussion offers a counter-argument that artifacts are not as pervasive in previous research as Sperling et al. imply and that their proposed method is subject to precisely the same limitations as earlier studies. Also discussed are some general guidelines of experimental design in this type of research to minimize the possibility that subjects will adopt an inappropriate response strategy that does not truly reflect their visual perceptions of three-dimensional form.

Prior knowledge and the desire for information.

Conducted 2 experiments to test D. Berlyne's theory that the desire for knowledge increases with the degree of conceptual conflict, and that new information serves to reduce the conflict. In Exp. I, 38 6th graders rated the extent to which they wished to explore 155 items of information. They also indicated their knowledge of these items. It was found that Ss wished mostly to experience those things about which they had a moderate amount of prior knowledge. In Exp. II, 43 11th graders indicated the extent of agreement with 24 controversial issues, and were then offered further information on each of the items. When Ss had no set attitude towards statements, they were less likely to reject additional information and more likely to accept the opportunity to receive general rather than biased information. Both studies support the authors' hypothesis that new information is sought when there is some prior knowledge and when conceptual conflict exists.
