Does feigning amnesia impair subsequent recall?

Defendants who are accused of serious crimes sometimes feign amnesia to evade criminal responsibility. Previous research has suggested that feigning amnesia might impair subsequent recall. In two experiments, participants read and heard a story about a central character, described as “you,” who was responsible for the death of either a puppy (Experiment 1) or a friend (Experiment 2). On free and cued recall tests immediately after the story, participants who had feigned amnesia recalled less than did participants who had recalled accurately. One week later, when all participants recalled accurately, participants who had previously feigned amnesia still performed worse than did participants who had recalled accurately both times. However, the participants who had formerly feigned amnesia did not perform worse than did a control group who had received only the delayed recall tests. Our results suggest that a “feigned amnesia effect” may reflect nothing more than differential practice at recall. Feigning amnesia for a crime need not impair memory for that crime when a person later seeks to remember accurately.     

Racial Peer Group Selection in African American High School Students

This study examined the influence of racial identity and other potential factors that may contribute to African American high school students' selection of a racial peer group. Results indicated that racial identity, feelings of racial similarity, and racial composition of one's neighborhood were differentially related to peer group selection. Esta investigación examinó la influencia de la identidad racial y otros factures potenciales que pueden contribua a la selección del grupo de compañeros racial de estudiantes de la preparatoria Africano Americanos. Cien y cuatro estudiantes Africano Americanos de una preparatoria multi‐étnica completaron medidas sobre su posición de identidad racial, los sentimientos de la similtud racial, susceptibilidad a la presión de sus compañeros, y la constitución racial su vencindario.     

Understanding the Vital Human Quest for Self-Esteem

ABSTRACT— Authors have long noted the human penchant for self-esteem. Experimental research has revealed that this desire for self-esteem has wide-ranging effects on cognition, emotion, and behavior. Terror management theory explains that this desire for self-esteem results from a fundamental need for psychological security, which is engendered by humans' awareness of their own vulnerability and mortality. A large body of evidence has supported this explanation. Specifically, substantial lines of research have shown that self-esteem buffers anxiety and reduces defenses against death and that reminders of mortality increase efforts to defend and bolster self-esteem. Complementary findings have helped clarify the role of culture in self-esteem striving and the ways in which people can vary in their level, stability, and sources of self-esteem. I conclude by briefly considering how this contemporary knowledge regarding the quest for self-esteem informs current events and daily life.     

Actions modulate attentional capture

The purpose of the present study was to determine whether the action system plays a role in determining which stimulus characteristics capture attention by assessing the interference effects caused by dynamic discontinuities that have similar attention-capturing properties, but different action affordances. Results revealed that offset distractors caused significant interference when onset targets were presented in a keypress task, but did not increase reaction times when the same onset targets were presented in a goal-directed aiming task In contrast, onset distractors caused interference when offset targets were presented in both keypress and aiming tasks. This pattern of results suggests that the attentional set, and thus the properties of stimuli that capture attention, is modulated by the interaction between stimulus and response expectations.     

The Roots of a 'Libertine' Slogan in 1 Corinthians 6:18

Taking as its starting point Jerome Murphy-O’Connor'sthesis that 1 Cor. 6:18b (‘every sin that a person commitsis outside the body’) represents a Corinthian slogan,this essay suggests that a social, cultural, and religious matrixexisted at Corinth from which the Corinthians could easily haveconstructed a slogan similar to that which Murphy-O’Connorenvisages. Available evidence suggests that this slogan wasdeveloped, in part, by the convergence of at least two majortributaries: (a) a non-Christian or Hellenistic-Roman stream(including popular philosophy and incipient Gnosticism), and(b) a Christian or Jesuanic current, flowing most probably fromPaul.     

Modern Sequential Analysis and Its Applications to Computerized Adaptive Testing

After a brief review of recent advances in sequential analysis involving sequential generalized likelihood ratio tests, we discuss their use in psychometric testing and extend the asymptotic optimality theory of these sequential tests to the case of sequentially generated experiments, of particular interest in computerized adaptive testing. We then show how these methods can be used to design adaptive mastery tests, which are asymptotically optimal and are also shown to provide substantial improvements over currently used sequential and fixed length tests.     

Choice

Understanding how and why analysands make the choices they do is central to both the clinical and the theoretical projects of psychoanalysis. And yet we know very little about the process of choice or about the relationship between choices and motives. A striking parallel is to be found between the ways choice is narrated in ancient Greek texts and the experience of analysts as they observe patients making choices in everyday clinical work. Pursuing this convergence of classical and contemporary sensibilities will illuminate crucial elements of the various meanings of choice, and of the way that these meanings change over the course of psychoanalytic treatment.     

Structured perceptual arrays and the modulation of Fitts's law: examining saccadic eye movements

On the basis of recent observations of a modulation of Fitts's law for manual pointing movements in structured visual arrays (J. J. Adam, R. Mol, J. Pratt, & M. H. Fischer, 2006; J. Pratt, J. J. Adam, & M. H. Fischer, 2007), the authors examined whether a similar modulation occurs for saccadic eye movements. Healthy participants (N = 19) made horizontal saccades to targets that appeared randomly in 1 of 4 positions, either on an empty background or within 1 of 4 placeholder boxes. Whereas in previous studies, placeholders caused a decrease in movement time (MT) without the normal decrease in movement accuracy predicted by Fitts's law, placeholders in the present experiment increased saccadic accuracy (decreased endpoint variability) without an increase in MT. The present results extend the findings of J. J. Adam et al. of a modulation of Fitts's law from the temporal domain to the spatial domain and from manual movements to eye movements.     

Is hypnotic suggestibility a stable trait?

The present study examined the trait-like nature of hypnotic suggestibility by examining the stability of hypnotic responsiveness in a test-retest design in which the procedures were administered either live or by audiotape. Contrary to the idea that hypnotizability is a largely immutable, stable trait, scores on the scale of hypnotic responsiveness decreased significantly at the second session. Measures of subjective experiences and expectancies accounted for a sizable portion of the variance in hypnotic responding, both at initial test and at retest. Participants became disengaged with the hypnotic procedures at retest. Participants who received the hypnotic induction by audiotape did not differ from participants who received it live. The results are consistent with sociocognitive and altered state theories of hypnosis, and underline the important role of subjective experiences in hypnotic responding.
