Biased lineups: sequential presentation reduces the problem.

Biased lineups have been shown to increase significantly false, but not correct, identification rates (Lindsay, Wallbridge, & Drennan, 1987; Lindsay & Wells, 1980; Malpass & Devine, 1981). Lindsay and Wells (1985) found that sequential lineup presentation reduced false identification rates, presumably by reducing reliance on relative judgment processes. Five staged-crime experiments were conducted to examine the effect of lineup biases and sequential presentation on eyewitness recognition accuracy. Sequential lineup presentation significantly reduced false identification rates from fair lineups as well as from lineups biased with regard to foil similarity, instructions, or witness attire, and from lineups biased in all of these ways. The results support recommendations that police present lineups sequentially.     

Rhythmical body movement in sleep: a brief review and treatment study

Vigorous and damaging head-banging and head and body-rocking can occur in normal subjects of average intelligence before and during sleep. Reports of behavioural treatments for this are reviewed. Data from the present case and others suggest that waking plus efficient response prevention is sufficient to substantially reduce or eliminate the activity even when the treatment has been withdrawn for up to one year. The aetiology of the activity is not understood. However, this case suggests that head- and body-rolling, when long-established, need not enhance the quality of sleep since this was unimpaired on completion of treatment and was possibly even improved by the elimination of the movements. The present case also demonstrates that the behaviour can be treated successfully even when considerable environmental stresses occur.     

Replications and Limitations of a Two-Factor Model of Child Witness Credibility

Two experiments are reported that test the idea that jurors perceive child witnesses in terms of a 2-factor model of credibility with the factors defined as cognitive ability and honesty (Leippe & Romanczyk, 1987; Ross, Millers, & Moran, 1989). In the first experiment, 300 mock jurors watched a realistic videotaped recreation of a sexual abuse trial and rated the credibility of the child witness. Mock jurors perceived the child witness in terms of 2 factors: cognitive ability and honesty. Only honesty predicted verdict. These findings were replicated in Experiment 2 ( N = 300) when only the child's testimony was presented and the perceptions of the child witness were not contaminated by the testimony of the other witnesses in the trial.

The relationship between reduplicated babble onset and laterality biases in infant rhythmic arm movements

This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles presented at midline for 1.5 min each. Rate of rattle shaking increased sharply from the pre-babble to the babble onset session; but there was no indication that this increase was specific to the right arm. This finding suggests that the link between babble onset and increased rhythmic arm activity may not be the product of language-specific mechanisms, but is rather part of a broader developmental process that is also perceptual and motor.     

Criteria for suicide-by-cop incidents

17 criteria for suicide-by-cop incidents were applied to 39 such incidents and 18 control incidents. Analysis indicated the criteria differentiated the two groups and may be useful for investigators.     

Developmental differences in the effects of repeated interviews and interviewer bias on young children's event memory and false reports

The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children's memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long delay made the most errors. Children interviewed repeatedly, regardless of interviewer bias, were more accurate and less likely to falsely claim that they played with a man. In free recall, among children questioned once after a long delay by the biased interviewer, 5-year-olds were more likely than were 3-year-olds to claim falsely that they played with a man. However, in response to direct questions, 3-year-olds were more easily manipulated into implying that they played with him. Findings suggest that interviewer bias is particularly problematic when children's memory has weakened. In contrast, repeated interviews that occur a short time after a to-be-remembered event do not necessarily increase children's errors, even when interviews include misleading questions and interviewer bias. Implications for developmental differences in memory and suggestibility are discussed.     

THE PERVERSITY OF INANIMATE OBJECTS: STIMULUS CONTROL BY INCIDENTAL MUSICAL NOTATION

Social cognition research suggests that incidental, environmental stimuli (e.g., business suits) can nonconsciously influence the degree to which behavioral dispositions (e.g., competitiveness) are expressed. Similarly, cognitive research suggests that incidental action-related objects (e.g., hammers) can prime action plans that then affect the speed with which a concurrent, intended action (e.g., power grip) is executed. However, whether incidental stimuli can instigate actions that run counter to one's current goals has yet to be determined. Moving beyond indirect effects, we show that such stimuli can directly cause the expression of undesired actions: Incidental stimuli resembling musical notation caused the systematic expression of unintended key presses in musicians, but not in nonmusicians. Moreover, the effect was found even when targets and distracters bore no apparent perceptual or semantic relation. We discuss the implications of these findings for models of action production and for social-cognitive concepts (e.g., applicability) regarding the limits of nonconscious processing.     

Goal agreement and relationship quality among college students and their parents

Two hundred eight parent–college student dyads (total N = 416) participated in the current study, which examined the link between goal agreement and perceived conflict within their relationships. Undergraduate participants (91 male, 117 female) completed a demographic form, a 65 items goal measure, and a measure of parental conflict. Parents (98 fathers, 110 mothers) were asked to rate the importance of the same 65 goals for their emerging adult children. College students tended to place more importance on independence, affect control, health, social relationships, and financial concern goals than their parents did, whereas parents placed more importance on moral and religious goals than their emerging adult children did. However, relative goal agreement between parents and college students was found to be moderately high. Those parent–college student dyads who experienced less conflict tended to have higher goal agreement, whereas those dyads with a higher level of conflict had lower goal agreement. These findings provide further evidence for the link between interpersonal relationships and the personality construct of goals.     

Cognitive Mechanisms Underlying Recovered-Memory Experiences of Childhood Sexual Abuse

ABSTRACT— People sometimes report recovering long-forgotten memories of childhood sexual abuse. The memory mechanisms that lead to such reports are not well understood, and the authenticity of recovered memories has often been challenged. We identified two subgroups of people reporting recovered memories of childhood sexual abuse. These subgroups differed dramatically in their cognitive profiles: People who recovered memories of abuse through suggestive therapy exhibited a heightened susceptibility to the construction of false memories, but showed no tendency to underestimate their prior remembering. Conversely, people who recovered memories of abuse spontaneously showed a heightened proneness to forget prior incidences of remembering, but exhibited no increased susceptibility to false memories. This double dissociation points to mechanisms that underlie recovered-memory experiences and indicates that recovered memories may at times be fictitious and may at other times be authentic.
