The time course of semantic and associative priming effects is different in an attentional blink task

When two targets are presented using rapid serial visual presentation (RSVP) and the interval between the targets is 200–500 ms, report of the second target is impaired, a phenomena known as the attentional blink (AB). This study examined the time course of semantic-only and associate–semantic priming effects during an AB task. Three RSVP experiments were conducted using targets that shared either a semantic-only or an associative–semantic relationship. The results of the three experiments demonstrated semantic-only priming effects at the shortest stimulus onset asynchronies (SOAs). Associative–semantic priming was evident at shorter and longer SOAs. This suggests that priming in an AB task is driven by conceptual overlap facilitating lexical access at short SOAs and with longer SOAs lexical access benefits from word associations links between targets.     

Jealousy,Shame, and the Rival

This essay is a critique of the two chapters on jealousy in Jerome Neu's book A Tear is an Intellectual Thing. The rival — as anobject of both fear and hatred — is of central importance in romantic jealousy, but it is here argued that the role of the rival cannot be fully understood in Neu's account of jealousy and that shame (not noted by Neu) must be seen as central to the concept of jealousy if the role of the rival is to be fully understood.     

Reliability and validity of the Yale Global Tic Severity Scale

To investigate the reliability and validity of the Yale Global Tic Severity Scale (YGTSS), 28 youth aged 6 to 17 years with Tourette's syndrome (TS) participated in the study. Data included clinician reports of tics and obsessive-compulsive disorder (OCD) severity, parent reports of tics, internalizing and externalizing problems, and child reports of depression and anxiety. All children participated in a 2nd YGTSS administration by the same rater 48 days later. Good internal consistency and stability were found for the YGTSS scores. YGTSS scores demonstrated strong correlations with parent-rated tic severity (r = .58-.68). YGTSS scores were not significantly related to measures of clinician ratings of OCD severity (r = .01-.15), parent ratings of externalizing and internalizing behavior (r = -.07-.20), and child ratings of depression (r = .02-.26) and anxiety (r = -.06 -.28). Findings suggest that the YGTSS is a reliable and valid instrument for the assessment of pediatric TS.     

Aggression in boys with attention deficit-hyperactivity disorder: Methylphenidate effects on naturalistically observed aggression,response to provocation,and social information processing

High and low-aggressive boys with attention deficit-hyperactivity disorder (ADHD) were compared and the effects of methylphenidate were examined on measures from three domains of aggression: (1) directly observed verbal and nonverbal aggressive behaviors exhibited in the context of a day treatment program, (2) aggressive responding when provoked during a laboratory task, and (3) social information processing patterns exhibited on tasks designed to tap the putative cognitive components of aggression. The high-aggressive (HA) and low-aggressive (LA) subgroups differed significantly on observational measures of aggression and on the laboratory provocation task, but the HA group showed more deviant cognitions on only one of the numerous measures of social information processing. Regarding medication effects on the direct observation measures, methylphenidate decreased aggression for both subgroups. On the laboratory provocation task, methylphenidate had only minimal effects. Significant drug effects were obtained on only two recall social information processing measures.     

Inhibition and aging: similarities between younger and older adults as revealed by the processing of unattended auditory information

The ability to selectively attend to an auditory stimulus appears to decline with age and may result from losses in the ability to inhibit the processing of irrelevant stimuli (i.e., the inhibitory deficit hypothesis; L. Hasher & R. T. Zacks, 1988). It is also possible that declines in the ability to selectively attend are a result of age-related hearing losses. Three experiments examined whether older and younger adults differed in their ability to inhibit the processing of distracting stimuli when the listening situation was adjusted to correct for individual differences in hearing. In all 3 experiments, younger and older adults were equally affected by irrelevant stimuli, unattended stimuli, or both. The implications for auditory attention research and for possible differences between auditory and visual processing are discussed.     

WHEN WOMEN IMBIBE

The present research examines how alcohol, or even the illusion of imbibing alcohol, affects women's perceived self-efficacy for avoiding HIV. Women ( N = 82) were randomly assigned to one of four conditions in a 2 (alcohol or no alcohol) X 2 (expect alcohol or not) balanced placebo design. After consuming alcoholic or nonalcoholic beverages, participants assessed their self-efficacy for HIV risk prevention. Both alcohol consumption and alcohol expectancy increased women's confidence that they could detect whether a potential partner was HIV positive simply by interacting with the potential partner.     

FROM CRITICAL REALISM TO A METHODOLOGICAL APPROACH: RESPONSE TO ROBBINS, VAN HUYSSTEEN, AND HEFNER

Abstract. Critical realism is a problematic philosophical doctrine that unnecessarily complicates attempts to relate theology and science. A more satisfactory approach employs the scientific methodology of Imre Lakatos for the reconstruction of theology along scientific lines. Theological research programs would automatically include auxiliary hypotheses of both theological and scientific origin.
