Memory as discrimination: What distraction reveals

Recalling information involves the process of discriminating between relevant and irrelevant information stored in memory. Not infrequently, the relevant information needs to be selected from among a series of related possibilities. This is likely to be particularly problematic when the irrelevant possibilities not only are temporally or contextually appropriate, but also overlap semantically with the target or targets. Here, we investigate the extent to which purely perceptual features that discriminate between irrelevant and target material can be used to overcome the negative impact of contextual and semantic relatedness. Adopting a distraction paradigm, it is demonstrated that when distractors are interleaved with targets presented either visually (Experiment 1) or auditorily (Experiment 2), a within-modality semantic distraction effect occurs; semantically related distractors impact upon recall more than do unrelated distractors. In the semantically related condition, the number of intrusions in recall is reduced, while the number of correctly recalled targets is simultaneously increased by the presence of perceptual cues to relevance (color features in Experiment 1 or speaker’s gender in Experiment 2). However, as is demonstrated in Experiment 3, even presenting semantically related distractors in a language and a sensory modality (spoken Welsh) distinct from that of the targets (visual English) is insufficient to eliminate false recalls completely or to restore correct recall to levels seen with unrelated distractors . Together, the study shows how semantic and nonsemantic discriminability shape patterns of both erroneous and correct recall.     

Self objects and development: Infant states of mind in an adolescent girl

In the context of Fordham's model of the deintegrating-reintegrating self, the paper discusses the total quality of the baby's earliest deintegrations and the nature of what Fordham terms the self object. The use of the term ‘whole object’ in Klein's and Fordham's terminology is explored and the self object is placed in the context of Jung's construct of the self and the archetypes. The paper illustrates how residues of the self object permeated a rule-making defensive structure in a 14-year-old girl and how the therapy provided an opportunity for the defence to loosen and for elements that had been locked, as potentials, in a ‘bump car’ self object, to unfold and develop. These elements included the possibility of enjoying the feminine qualities of being a girl and exploration of the mother-infant couple and its confusions in her inner world. In addition, they included getting in touch with an infant, vulnerable part of her personality and modifying a habitual defence which was to take refuge in projective identification with an aggressive, omnipotent phantasied brother. Another important element unfolded through the separation of herself from the idealized, precept-daughter in her mother's mind. A fixed projective identification with a self object became more flexible as the object was explored and developed, and its archetypal absoluteness modified, in the therapeutic relationship.     

A Cross-Country Evaluation of Cheating in Academia—A Comparison of Data from the US and the Czech Republic

In this study, we examine differences in cheating behaviors in higher education between two countries, namely the United States and the Czech Republic, which differ in many social, cultural and political aspects. We compare a recent (2011) Czech Republic survey of 291 students to that of 268 students in the US (Klein et al., 2007). For all items surveyed, CR students showed a higher propensity to engage in cheating. Additionally, we found more forms of serious cheating present in the Czech sample. In all cases, the differences between the US and Czech samples were statistically significant.     

Selective and faithful imitation at 12 and 15 months

Research on imitation in infancy has primarily focused on what and when infants imitate. More recently, however, the question why infants imitate has received renewed attention, partly motivated by the finding that infants sometimes selectively imitate the actions of others and sometimes faithfully imitate, or overimitate, the actions of others. The present study evaluates the hypothesis that this varying imitative behavior is related to infants' social traits. To do so, we assessed faithful and selective imitation longitudinally at 12 and 15 months, and extraversion at 15 months. At both ages, selective imitation was dependent on the causal structure of the act. From 12 to 15 months, selective imitation decreased while faithful imitation increased. Furthermore, infants high in extraversion were more faithful imitators than infants low in extraversion. These results demonstrate that the onset of faithful imitation is earlier than previously thought, but later than the onset of selective imitation. The observed relation between extraversion and faithful imitation supports the hypothesis that faithful imitation is driven by the social motivations of the infant. We call this relation the King Louie Effect: like the orangutan King Louie in The Jungle Book, infants imitate faithfully due to a growing interest in the interpersonal nature of interactions.

Inhibition of return can be associated with object identity but not with object category

In this study, pre-schoolers and a comparison sample of fifth graders and high school students were presented with prediction tasks that varied by content of the base rate information (perceptual vs semantic) either presented alone (simple task) or accompanied by individuating data (complex task). Base rate choices, confidence scores, and explanations of the choices were registered. It is assumed that the presence of content effects in the processing of the base rates is in favour of a mental model account. Results indicated that pre-schoolers are able to build one-dimensional models with perceptual base rates in simple tasks. Fifth graders and high school students are able to build one-dimensional models with both types of content in simple tasks, as well as two-dimensional models in complex tasks. There is a local facilitation effect of semantic contents for fifth graders that disappears for high-school students. Consistency between subjects' choices, confidence scores and rationales depends on the subjects' grade, the number of sources involved, and the base rate content. Developmental trends are discussed in the light of previous research within formal, heuristic, and mental model approaches.     

Maintaining Life Satisfaction: The Role of Positive Cognitive Bias

Recent research into population standards of life satisfaction has revealed a remarkable level of uniformity, with the mean values for Western populations clustering at around three-quarters of the measurement scale maximum. While this seems to suggest the presence of a homeostatic mechanism for life satisfaction, the character of such a hypothetical device is uncertain. This paper proposes that well-being homeostasis is controlled by positive cognitive biases pertaining to the self. Most particular in this regard are the positive biases in relation to self-esteem, control and optimism. Past controversies in relation to this proposition are reviewed and resolved in favour of the proposed mechanism. The empirical data to support this hypothesis are discussed in the context of perceived well-being as an adaptive human attribute.     

Effects of gender and sexuality on judgements of victim blame and rape myth acceptance in a depicted male rape

Relatively few studies have investigated judgements towards male rape, and no published studies have investigated gay men's judgements towards this offence. The current study investigated the effects of gender and sexuality on victim blame and male rape myth acceptance in the depicted rape of a gay man. It was predicted that heterosexual men would make the most anti‐victim judgements, while gay men would make the most pro‐victim judgements. One hundred and fifty members of the UK population read a scenario that depicted a male rape, and then completed a questionnaire that measured blame and rape myths. As predicted, heterosexual men endorsed more rape myths and blamed the victim more than heterosexual women or gay men. Gay men made the most pro‐victim judgements overall. Results are discussed in relation to homophobia and traditional gender roles. Copyright © 2003 John Wiley & Sons, Ltd.
