The eye gaze direction of an observed person can bias perception,memory, and attention in adolescents with and without autism spectrum disorder

The reported experiments aimed to investigate whether a person and his or her gaze direction presented in the context of a naturalistic scene cause perception, memory, and attention to be biased in typically developing adolescents and high-functioning adolescents with autism spectrum disorder (ASD). A novel computerized image manipulation program presented a series of photographic scenes, each containing a person. The program enabled participants to laterally maneuver the scenes behind a static window, the borders of which partially occluded the scenes. The gaze direction of the person in the scenes spontaneously cued attention of both groups in the direction of gaze, affecting judgments of preference (Experiment 1a) and causing memory biases (Experiment 1b). Experiment 2 showed that the gaze direction of a person cues visual search accurately to the exact location of gaze in both groups. These findings suggest that biases in preference, memory, and attention are caused by another person’s gaze direction when viewed in a complex scene in adolescents with and without ASD     

The testing effect: The role of feedback and collaboration in a tertiary classroom setting

Successful retrieval on a test compared to just re‐studying material improves long‐term retention—a phenomenon called the ‘testing effect’. This study investigated the role of feedback and collaborative testing on the retention of course material in a tertiary educational setting. Tested material was better retained relative to non‐tested material (testing effect), and feedback facilitated correction of errors. Group testing produced higher performance on the initial, but not final test performance, compared to individual testing. This set of findings suggests that to encourage long‐term retention, educators should utilise individual formative testing with feedback; theoretical implications are also discussed.

Search strategies in decision making: the success of “success”

Examination of search strategies has tended to focus on choices determined by decision makers' personal preferences among relevant cues, and not on learning cue‐criterion relationships. We present an empirical and rational analysis of cue search for environments with objective criteria. In such environments, cues can be evaluated on the basis of three properties: validity (the probability that a cue identifies the correct choice if cue values differ between alternatives); discrimination rate (the proportion of occasions on which a cue has differing values); and success (the expected proportion of correct choices when only that cue can be used). Our experiments show that though there is a high degree of individual variability, success is a key determinant of search. Furthermore, a rational analysis demonstrates why success‐directed search is the most adaptive strategy in many circumstances. Copyright © 2004 John Wiley & Sons, Ltd.     

Predictors of Risky and Precautionary Sexual Behaviors Among Single and Married White Women1

Risky and precautionary sexual behaviors were examined in a community sample of 260 single and married/cohabitating White women. Structural equation modeling was used to assess the ability of age, socioeconomic status (SES), marital status, religiosity, and 9 health belief constructs to predict risky sexual behavior with one's partner, using a barrier method of birth control, unintended pregnancies, and number of sexual partners in the past year. The pattern of results suggests that single White women appear to feel more vulnerable to HIV and STD infection and more likely to engage in risky sexual behavior than do married White women. The discussion focuses on the importance of sociocultural factors in understanding risk behaviors within the social context of relationship status, the complexity of the concept of risk reduction, and the need for going beyond the health belief model in order to develop different HIV prevention strategies for single and married White women.     

The subliminal mere exposure effect does not generalize to structurally related stimuli.

R.F. Bornstein (1994) questioned whether subliminal mere exposure effects might generalize to structurally related stimuli, thereby providing evidence for the existence of implicit learning. Two experiments examined this claim using letter string stimuli constructed according to the rules of an artificial grammar. Experiment 1 demonstrated that brief, masked exposure to grammatical strings impaired recognition but failed to produce a mere exposure effect on novel structurally related strings seen at test. Experiment 2 replicated this result but also demonstrated that a reliable mere exposure effect could be obtained, provided the same grammatical strings were presented at test. The results suggest that the structural relationship between training and test items prevents the mere exposure effect when participants are unaware of the exposure status of stimuli, and therefore provide no evidence for the existence of implicit learning.     

Structural behavioural analysis as a basis for discriminating between genuine and simulated rape allegations

This paper explores the potential utility of structural behavioural analysis as a basis for discriminating between genuine and simulated accounts of rape. Structural analysis examines the coherence of the combination of behaviours in the account based against the co‐occurrence of behaviours in genuine accounts. Three analyses compared 142 genuine rape with 30 simulated statements in terms of the base rates of behaviours reported within the statements, and in terms of the behavioural coherence of each statement to an established behavioural structure. Results suggest that genuine statements tend to report a larger total number of behaviours than simulated statements; that pseudo‐intimate behaviours are significantly more often reported in genuine statements while some violent behaviours are more frequently reported in simulated statements; and that simulated statements are less behaviourally coherent than genuine statements. We concede the many limitations of the study but argue that results provide tentative evidence that false claimants, not fully appreciating the phenomenological experience of rape, overemphasise the significance of violent and demeaning behaviour whilst underplaying the significance of pseudo‐intimate behaviour.

Reference to Emotion States During Narrative Co‐Construction With Three‐Year‐Old Kibbutz Children: Comparison of Mother–Child and Metapelet–Child Dyads

In this study of young kibbutz children, we considered similarities and differences between mother–child dyads and metapelet (nonmaternal female caregiver)–child dyads on their rates of mentioning positive and negative emotion states and emotion calls during narrative co‐construction from a text‐free picture book illustrating emotionally charged situations. Thirty‐two kibbutz children approximately 3 years of age, their mothers, and their metaplot (i.e., plural of metapelet) were observed during co‐construction from the picture book. All participants (mothers, metaplot, children with mothers, and children with metaplot) mentioned more negative emotion states and emitted more negative emotion calls than positive ones. Children mentioned less emotion states than adults. No differences were found between mothers and metaplot in the number of emotion states mentioned, but mothers used significantly more emotion calls than did the metaplot, and their children tended to reciprocate. The influence of the context and type of relationship on emotion regulation is discussed.     

"Living Our Faith:" The Lenten Pastoral Letter of the Bishops of Malawi and the Shift to Multiparty Democracy, 1992–1993

From 1964 to 1993, Dr. Hastings Kamuzu Banda ruled the nation of Malawi by a singular mixture of terror and ritualized paternalism, relying on religious institutions to bolster his own moral authority. In the changing global and regional political context of the early 1990s, however, it was the Roman Catholic bishops of Malawi who challenged the prevailing culture of silence. In the lenten pastoral letter entitled "Living Our Faith," the seven bishops reproached the Banda regime for its authoritarianism. Relying on New Testament images of Christians as inherently free, the bishops ultimately contributed to the development of representative democracy. Acting not as biased proponents of specific political groups but rather as the champions of government accountability and human dignity, Malawan Catholic clerics and the external rituals and symbols of their faith have attained (at least in the short term) a greater prestige and popular appeal in a religiously heterodox nation.     

Multisensory integration in multiple reference frames in the posterior parietal cortex

Spatial information processing takes place in different brain regions that receive converging inputs from several sensory modalities. Because of our own movements—for example, changes in eye position, head rotations, and so forth—unimodal sensory representations move continuously relative to one another. It is generally assumed that for multisensory integration to be an orderly process, it should take place between stimuli at congruent spatial locations. In the monkey posterior parietal cortex, the ventral intraparietal (VIP) area is specialized for the analysis of movement information using visual, somatosensory, vestibular, and auditory signals. Focusing on the visual and tactile modalities, we found that in area VIP, like in the superior colliculus, multisensory signals interact at the single neuron level, suggesting that this area participates in multisensory integration. Curiously, VIP does not use a single, invariant coordinate system to encode locations within and across sensory modalities. Visual stimuli can be encoded with respect to the eye, the head, or halfway between the two reference frames, whereas tactile stimuli seem to be prevalently encoded relative to the body. Hence, while some multisensory neurons in VIP could encode spatially congruent tactile and visual stimuli independently of current posture, in other neurons this would not be the case. Future work will need to evaluate the implications of these observations for theories of optimal multisensory integration.Edited by: Marie-Hélène Giard and Mark Wallace
