Memory impairment and Benign Epilepsy with centrotemporal spike (BECTS): A growing suspicion

Benign Epilepsy with centrotemporal spikes (BECTS) is considered a benign type of epilepsy; nevertheless a significant number of children present clear and heterogeneous cognitive deficits such as memory disturbances. Thus far, evidence about memory impairment has been less than conclusive. To clarify the quality of memory functioning in BECTS children, an analysis of existing findings has been conducted trying to identify the type of memory deficits and their underlying factors. Short- and long-term declarative memory are impaired in BECTS children, with both verbal and non-verbal material; co-occurrence of attentional, linguistic and behavioral disturbances is reported. In children with continuous spikes and waves during the slow-wave sleep pattern the normal downscaling of slow-wave activity is absent, disrupting plastic brain processes of sleep-related memory consolidation. In BECTS children, NREM sleep interictal epileptiform discharges (IED) may interfere in the dialogue between temporal and frontal cortex, causing declarative memory deficits: the role of NREM sleep IED acquires a special importance, leading to methodological guidance and suggesting aims for future researches in the field of childhood neuroscience.     

Detecting and identifying change: additions versus deletions

The recognition of changes in the features of objects was examined as a function of the nature of the change (additions, deletions, no change). In two experiments we assessed both detection (noticing whether the stimulus had changed) and identification (specifying the exact nature of the change). Both detection and identification were expected to depend upon the subject's awareness of the subsequent recognition tasks while the original stimuli were encoded. In Experiment 1, subjects were not aware of subsequent detection and identification tasks while they initially viewed study slides of the to-be-changed stimuli. During the subsequent presentation of the test stimuli, detection and identification were superior for additions. On the other hand, in Experiment 2 when subjects were aware of the subsequent recognition tasks while viewing each study slide, a detection advantage for deletions obtained. Identification performance depended upon a further factor, whether the features of a stimulus were codable. Only in codable stimuli were deletions easier to identify than additions. The differences between the two experiments in detecting and identifying additions versus deletions are consistent with Tversky's (1977) research that stresses the importance of specifying which representation (the study stimulus or the test stimulus) is the subject of comparison in the comparative judgment.     

Extradyadic romantic involvement: Moderating effects of sociosexuality and gender

The present study examined whether relationships of self-reported depression and suicidality to gender roles or gender are moderated by the type of stressful life events that individuals experience. The focus was on events in stereotypic male (achievement) versus female (interpersonal) domains. This study of 290 women and 247 men undergraduates employed the Beck Depression Inventory (BDI), the Personal Attributes Questionnaire and a measure of recent negative life events. In the presence of high achievement stress, high masculinity was related to low suicidality for men. In the presence of high interpersonal stress, high femininity was related to low self-reported depression for women. These findings were interpreted as consistent with the androgyny model of adjustment. However, independent of gender roles, high interpersonal stress was related to high self-reported depression more strongly among women than among men. Suicidality was related to interpersonal events for women and achievement events for men. These findings were interpreted as consistent with the self-schema model of depression.The authors gratefully acknowledge Jane Karyl and Ann Shields for substantial assistance with data collection and management and Michael L.

Social Comparisons of One's Own With Others' Attitudes Toward Casual and Responsible Sex1

College students perceive their risks for negative outcomes from sexual behavior as lower than that of their peers. We examined whether similar biases would occur when undergraduates rated their own, their close friends', and the typical college student's attitudes regarding casual sex and sexual responsibility. Participants rated their own attitudes relative to all others' as the least permissive and most sexually responsible. Close friends' attitudes were rated as less permissive and more responsible than the average college student's. Finally, individuals with unrestricted sociosexual orientations and men attributed more permissive and less sexually responsible attitudes to both themselves and close friends than did individuals with restricted sociosexual orientations and women. These latter effects were absent when rating the typical college student.     

BRIEF REPORT Interpretation of death‐relevant ambiguous stimuli as a function of death threat

According to G.A. Kelly's (1955) Personal Construct Theory, people are threatened by personal death to the extent that their conceptions of death are inconsistent with their conceptions of their present selves. As an individual difference factor, death threat predicts how people respond to death‐relevant situations and stimuli. To test the hypothesis that high death‐threat (relative to low death‐threat) persons will engage in greater denial when assigning meaning to ambiguous stimuli, college students viewed inkblots and chose between a nondeath‐relevant interpretation and a death‐relevant interpretation. As hypothesised, high death‐threat participants endorsed fewer death‐relevant interpretations than did low death‐threat participants. Self‐reported conscious fear of death did not predict this avoidance. Results are discussed in the light of historical and current work on psychological responses to death.
