Repetition of highly similar messages and attitude change.

Predicted that message repetition would increase positive attitudes in a situation where highly similar communications are used. 5 similar advertisements (i.e., those using the same basic arguments but differing in the phrasing and order of points raised) served as stimulus messages and were sequentially presented with attitude being measured by a cognitive response analysis of thoughts recorded by 50 undergraduates. Results support the prediction of a positive relationship between the number of presentations and attitude. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Repetition priming and change in functional ability in older persons without dementia.

Adverse consequences such as institutionalization and death are associated with compromised activities of daily living in aging, yet there is little known about risk factors for the development and progression of functional disability. Using generalized linear models, the authors examined the association between the ability to benefit from repetition and rate of change in functional ability in 160 nondemented elders participating in the Religious Orders Study. Three single-word repetition priming tasks were administered that varied in the degree to which visual-perceptual or conceptual processing was invoked. Decline in functional ability was less rapid, during follow-up of up to 10 years, in persons with better baseline priming performance on a task known to draw on both visual-perceptual and conceptual processing (word-stem completion). By contrast, change in functional ability was not associated with priming on tasks that are known to draw primarily on either visual-perceptual (threshold word-identification) or conceptual (category exemplar production) processing. The results are discussed in terms of a common biological substrate in the inferotemporal neocortex, supporting efficient processing of meaningful visual-perceptual experience and proficient performance of activities of daily living.

Repetition blindness: Levels of processing.

Repetition blindness (RB) is the failure to detect or recall repetitions of words in rapid serial visual presentation. Experiment 1 showed that synonym pairs are not susceptible to RB. In Experiments 2 and 3, RB was still found when one occurrence of the word was part of a compound noun phrase. In Experiment 4, homonyms produced RB if they were spelled identically (even if pronounced differently) but not if spelled differently and pronounced the same. Similarly spelled but otherwise unrelated word pairs appeared to generate RB (Experiment 5), but Experiment 6 produced an alternative account. Experiments 7 and 8 demonstrated that repeated letters are susceptible to RB only when displayed individually, not as part of two otherwise different words. It is concluded that RB can occur at either an orthographic (possibly morphemic) level or a case-independent letter level, depending on which unit (words or single letters) is the focus of processing.

Repetition priming and associative priming of face recognition: Evidence from event-related potentials.

Face recognition can be facilitated by previous presentation both of the same face and of an associated person's face. In Experiment 1, the effects of face repetition and associative priming on event-related potentials (ERPs) were compared. Repetition decreased reaction times (RTs) and modulated both early (180–290 ms) and late ERPs beyond 310 ms. Associative priming caused a topographically equivalent late ERP modulation, although RTs and early ERPs were unaffected. The results suggest that repetition acted on an early processing locus, presumably the activation of face representations. Both repetition and associative priming affected a relatively late locus, probably the activation of person-related semantic information. In Experiment 2, face repetitions were omitted and associative priming effects were observed both in ERPs and RTs. This indicates that ERPs may reflect automatic aspects of associative priming more directly than do RTs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Repetition effects with categorizable stimulus and response sets.

The repetition effect refers to the finding that reaction times (RTs) are faster on trial n when the stimulus presented and/or the response required is the same as on trial n?–?1 than when it is different. Five experiments examined the importance of stimulus features and response features in obtaining the repetition effect. Exp 1 demonstrated a need for the stimuli to be categorically mapped to responses for a response repetition effect to be observed. Exps 2–5 showed that the repetition effect can be obtained across responding hands when spatial information (Exps 2 and 4) or finger information (Exps 2 and 5) is consistent across hands but not when these sources of information are eliminated (Exp 3). The results are in agreement with expectations developed from salient-features coding and with the inclusive links hypothesis proposed by H. Pashler and G. Baylis (1991).

Electrodermal activity and schizophrenia: The problem of stimulus intensity modulation.

Recent reviews on electrodermal activity and schizophrenia have cited both hyperreactivity and hyporeactivity in groups of schizophrenics. One problem concerning the interpretation of hyporeactivity is that of stimulus-intensity modulation. This problem is defined, and it is suggested that researchers interested in basic neurophysiological activity of schizophrenics employ a nonstressful experimental procedure.

Electrodermal habituation and subjective response: Effects of manifest anxiety and autonomic arousal.

Studied the effects of cortical function and individual differences on galvanic skin response (GSR) habituation to tones of low and moderate intensity. 40 female undergraduates were divided into high- and low-anxious groups, on the basis of their Taylor Manifest Anxiety scale scores, and into high- and low-arousal groups, on the basis of their resting-level GSR activity. High-anxious Ss perceived nonchanging, nonnoxious moderate and low tones as increasing in intensity over trials while their electrodermal responses to the tones were habituating. Although the low-anxious group and the high- and low-arousal groups also showed electrodermal habituation, there were no significant effects of trials for intensity ratings.

Repetition and the SNARC effect with one- and two-digit numbers.

The SNARC (Spatial Numerical Association of Response Codes) effect is the finding that small numbers elicit faster left than right responses and large numbers elicit faster right than left responses. This effect suggests that numbers activate left-right magnitude-laterality codes and that these codes interact with the selection of left-right responses. In the present research, subjects made parity decisions for one-digit numbers (in Experiment 1) and two-digit numbers (in Experiment 2), and we examined the effect of stimulus repetition on the SNARC effect. With single-digit stimuli, responses were faster and the SNARC effect was eliminated when stimuli were identical on successive trials. With two-digit stimuli, responses were faster when the ones digit was repeated, but the SNARC effect was found regardless of whether the digit was repeated or not. We argue that magnitude-laterality codes are activated in the process of accessing number information in memory and that this process can be short circuited if the visual stimulus matches that on the previous trial. Thus, no SNARC effect is found in Experiment 1 when identical stimuli are presented on successive trials. However, this result is not found in Experiment 2 because successive stimuli do not match even if the ones digit is repeated. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Fluent rereading: Repetition, automaticity, and discrepancy.

Six experiments examined readers' sensitivity to discrepancies introduced into familiar texts. Across 4 or 5 trials, Ss crossed out misspellings as they read. Reading times decreased across repeated readings, and even though misspellings differed on every reading, their detection remained constant or improved across readings. Thus, reading became fluent but remained accurate across experiences. On the final reading, small discrepancies were unexpectedly introduced into the familiar texts. Results showed clear sensitivity to discrepancies in visual features (Exps 1, 2, and 5) and in lexical and semantic characteristics (Exps 3, 4, and 6) of familiar texts. Exps 5 and 6 showed that this sensitivity was on-line, occurring in the interval in which the discrepancy was encountered. The findings are discussed in terms of episodic transfer across repetitions.

Associative and nonassociative theories of the UCS preexposure phenomenon: Implications for Pavlovian conditioning.

Excitatory Pavlovian conditioning of a discrete CS is attenuated by prior exposure to the UCS. The UCS preexposure phenomenon is observed in a variety of Pavlovian conditioning procedures as diverse as eyelid conditioning, the conditioned emotional response, and conditioned taste aversion learning. This article discusses the variables that affect the UCS preexposure phenomenon and uses this information in evaluating both associative and nonassociative accounts of the phenomenon. At least one associative account, based on context blocking, and at least one nonassociative account, based on central habituation of the emotional response to the UCS, remain viable.

Age-related decline of visual processing components in change detection.

Previous research has suggested that an age-related decline in change detection may be due to older adults using a more conservative response criterion. However, this finding may reflect methodological limitations of the traditional change detection design, in which displays are presented continuously until a change is detected. Across 2 experiments, the authors assessed adult age differences in a version of change detection that required a response after each pair of pre- and postchange displays, thus reducing the potential contribution of response criterion. Older adults performed worse than younger adults, committing more errors and requiring a greater number of display cycles for correct detection. These age-related performance declines were substantially reduced after controlling statistically for elementary perceptual speed. Search strategy was largely similar for the 2 age groups, but perceptual speed was less successful in accounting for age-related variance in detectability when a more precise spatial localization of change was required (Experiment 2). Thus, the negative effect of aging in the present tasks lies in a reduction of detection efficiency due largely to processing speed, though some strategy-level effects may also contribute.

Aging and Repetition Effects: Separate Specific and Nonspecific Influences.

The research reported in this article focuses on processes that contribute to the repetition effect in 2-alternative forced-choice tasks and on how these processes change with age. An analytical approach is presented that allows researchers to discriminate between 2 components of performance. The results of Experiment 1 show that differences in the relative contributions of these 2 processes can produce differences in repetition effects between younger and older adults. Furthermore, as in the negative priming domain, increasing the contribution of 1 of these 2 components can eliminate this age difference. Together, the results argue against the practice of attributing age differences in repetition effects to deficits in any single cognitive process.

Repetition of semantic comparisons: Temporary and persistent priming effects.

Two experiments tested the involvement of both abstract semantic memory representations and instance-specific memory for feature encoding in repetition effects for a semantic processing task. Experiment 1 showed that a relatively small amount of facilitation (10%–25%) was attributable to memory for instance-specific features (typography) of repeated trials. Although small, this effect showed no decay over repetition lags investigated, suggesting persistent memory for encoded features or encoding processes. Experiment 2 showed that facilitation for semantically related repetitions was short-lived compared with facilitation for lexically exact repetitions. This suggested that priming of abstract semantic memory may be involved in temporary but not persistent repetition effects. Individual differences analyses supported the conclusion that despite the increased semantic complexity of this repetition priming task over those previously used, abstract semantic memory representations were not involved in persistent repetition effects.

Repetition and incomplete mourning: The intergenerational transmission of traumatic themes.

Suggests that the successful interchange of giving and receiving between parents and their children enables children to move toward independence with good conscience. When this interchange breaks down, it may become fixed around a traumatic theme. Identification with the parental aggressor of the traumatic theme may then become the source for a characterological immersion in the compulsion to repeat the same aggression with the next generation. The intergenerational transmission of traumatic themes to children is viewed as a manifestation of the identification with the aggressor and is contrasted with the process of mourning one's childhood. Mourning is viewed as a process of reintegrating repressed wishes for "what could have been." This enables one to relinquish the necessity that those wishes be fulfilled, and makes it possible to give a better life to one's children.

UCS intensity and instructional set in classical eyelid conditioning: Discrimination conditioning and signal-detection analysis.

Conducted discrimination eyelid conditioning at 2 UCS intensities under inhibitory, neutral, and facilitatory instructional sets, in a experiment involving 144 undergraduates in 6 groups. Instructional set yielded receiver operating characteristic curves that were reasonably straight lines on a normal deviate plot. The tentative conclusion from signal-detection theory of an equal discriminability function across instructional sets was contrasted with 4 indices of discrimination, indicating significant but mutually contradictory changes in discrimination as a function of instructional set. Discrimination differences were produced by UCS intensity, particularly under the neutral instructions. (French summary) (16 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Videotaped interrogations and confessions: A simple change in camera perspective alters verdicts in simulated trials.

Prior research has indicated that altering the perspective from which a videotaped confession is recorded influences assessments of the confession's voluntariness. The authors examined whether this camera perspective bias persists in more ecologically valid contexts. In Study 1, neither a realistic videotaped trial simulation nor potentially corrective judicial instruction was sufficient to mitigate the prejudicial effect of camera perspective on mock jurors' assessments of voluntariness or on their all-important final verdicts. Study 2 suggests that perhaps the best camera perspective to use is one that focuses trial fact finders' attention on the interrogator, as this particular vantage point may facilitate decision makers' capacity to detect coercive influences, which in turn could, in some cases, improve assessments of the confession's reliability.

Electrodermal activity in euthymic patients with affective disorders: One-year retest stability and the effects of stimulus intensity and significance.

Examined the effects of stimulus intensity and meaningfulness on the electrodermal activity (EDA) of patients with remitted major affective disorders in 22 unipolar (mean age 41 yrs), 22 bipolar (mean age 38.5 yrs), and 26 normal control (mean age 41.5 yrs) Ss. 29 of the affective disorder patients and 23 of the control Ss participated in a study of EDA conducted 1 yr earlier by the 1st author and colleagues (1983). Ss blew up a balloon until it burst and were exposed to 8 86-db tones, 12 105-db tones and 8 familiar sounds that reached a peak intensity of 105 db. Skin conductance was recorded bilaterally and averaged over hands. Results indicate that, compared to the control Ss, the affective disorder patients responded significantly less to the balloon task, the 105-db tones, and the familiar sounds. The affective-disorder groups had lower tonic levels than did the controls. Several measures of EDA displayed moderately high 1-yr retest stability. The pattern of findings is consistent with the hypothesis that depressed EDA may be a trait characterizing those who are prone to major affective disorder.

Beyond clinical trials: Generalizing from research to practice.

Suggests that clinical trials, or evaluations of psychotherapy techniques in clinical settings with patient populations, play a pivotal role in treatment research. Well-controlled psychotherapy trials provide a test of what treatment can do under conditions in which procedures such as therapist training and monitoring and the integrity of treatment are optimal. Methods designed to reduce the hiatus in how treatments are implemented, monitored, and evaluated in clinical research and practice include developing standardized assessment and treatment packages that can be implemented by practitioners, altering the manner in which clinical training is implemented and evaluated, training clinicians in strategies to evaluate their own clinical work, and conducting clinical replication case studies as a way to evaluate treatment applications in clinical practice. These alternatives combine standardization, training, evaluation, and clinical practice to help increase the generality of research findings to clinical work and to help merge research and clinical priorities.

Repetition blindness has a perceptual locus: Evidence from online processing of targets in RSVP streams.

Four experiments tested whether repetition blindness (RB; reduced accuracy reporting repetitions of briefly displayed items) is a perceptual or a memory-recall phenomenon. RB was measured in rapid serial visual presentation (RSVP) streams, with the task altered to reduce memory demands. In Experiment 1 only the number of targets (1 vs. 2) was reported, eliminating the need to remember target identities. Experiment 2 segregated repeated and nonrepeated targets into separate blocks to reduce bias against repeated targets. Experiments 3 and 4 required immediate "online" buttonpress responses to targets as they occurred. All 4 experiments showed very strong RB. Furthermore, the online response data showed clearly that the 2nd of the repeated targets is the one missed. The present results show that in the RSVP paradigm, RB occurs online during initial stimulus encoding and decision making. The authors argue that RB is indeed a perceptual phenomenon.

Components of activation: Repetition and priming effects in lexical decision and recognition.

Examined activation decay functions in 4 experiments in which 52 undergraduates performed 2 different tasks: lexical decision and word recognition. Activation (amount of facilitation) was measured both for item repetition and for priming between newly learned associates. Results indicate that there were at least 3 different components of activation: a short-term component that decayed with 1 or 2 intervening items and appeared to be common to priming and repetition, an intermediate component for repetition in recognition, and a long-term component for repetition.
