Retrospective assessment of childhood sexual and physical abuse: a comparison of scaled and behaviorally specific approaches

This study compared retrospective reports of childhood sexual and physical abuse as assessed by two measures: the Childhood Trauma Questionnaire (CTQ), which uses a Likert-type scaling approach, and the Computer Assisted Maltreatment Inventory (CAMI), which employs a behaviorally specific means of assessment. Participants included 1,195 undergraduate students recruited from three geographically diverse universities. Agreement was high across the two measures in the classification of victim status (92% and 80% for sexual and physical abuse, respectively). However, the CTQ classified more participants as sexually abused than did the CAMI, whereas the opposite trend was found for physical abuse. For child physical abuse, many participants reporting abusive acts on the CAMI scored below the cut-point for physical abuse on the CTQ. Classification differences for both types of abuse were largely unrelated to demographic factors, socially desirable responding, or self-reported withholding of information. The implications of these results are discussed in light of future research using retrospective methods of assessing childhood abuse.     

Beyond faces and modularity: the power of an expertise framework

Studies of perceptual expertise typically ask whether the mechanisms underlying face recognition are domain specific or domain general. This debate has so dominated the literature that it has masked the more general usefulness of the expertise framework for studying the phenomenon of category specialization. Here we argue that the value of an expertise framework is not solely dependent on its relevance to face recognition. Beyond offering an alternative to domain-specific accounts of face specialization in terms of interactions between experience, task demands, and neural biases, expertise studies reveal principles of perceptual learning that apply to many different domains and forms of expertise. As such the expertise framework provides a unique window onto the functional plasticity of the mind and brain.     

Studies of the vicarious traumatization of college students by the September 11th attacks: effects of proximity, exposure and connectedness

From mid-October 2001 through the end of November 2001, we collected fairly large sets of questionnaires from undergraduates at three public universities (Albany, NY, n = 507, Augusta, GA, n = 336, Fargo, ND, n = 526 ) to assess rate of acute stress disorder (ASD) and level of ASD symptoms following the September 11th attacks, rate of current posttraumatic stress disorder (PTSD) and level of PTSD symptoms, and current level of depressive symptoms resulting from the September 11th attacks. We also gathered information on exposure to media coverage of the attacks, connectedness to the World Trade Center (WTC) and personnel there, and degree of engagement in reparative acts such as giving blood, attending vigils. We found higher levels of ASD, ASD symptoms, PTSD and PTSD symptoms as a function of geographical proximity to New York City (and within the Albany site, proximity of students' homes) and gender. Exposure (hours of TV watched) was a predictor in some instances as was connectedness to WTC victims. ASD symptoms were the strongest predictor of subsequent PTSD symptoms. Path models accounted for over 60% of the variance in PTSD symptoms.     

Posttraumatic stress and depressive symptoms in a college population one year after the September 11 attacks: the effect of proximity

As a follow-up to our earlier report [Behav. Res. Ther., in press] on the level of posttraumatic stress symptoms (PTSS), depressive symptoms, and frequency of diagnoses of probable posttraumatic stress disorder (PTSD) among college students at three public universities (Albany, NY, Augusta, GA, and Fargo, ND) resulting from the September 11, 2001. Terrorist attacks, we surveyed comparable groups of students (total, n = 1313) from these three institutions in the weeks following the first anniversary (2002) of the attacks. We found proximity effects (Albany higher than Augusta which was higher than Fargo) for PTSS and depressive symptoms but not for frequency of diagnoses of probable PTSD. Within the Albany site data, proximity of county of residence to New York City (NYC) also showed a proximity effect on PTSS. Although depressive symptoms were significantly different in 2002 versus 2001, the arithmetic differences in PTSS or in frequency of diagnoses of probable PTSD were not significant. The September 11 attacks continued to exert a psychic toll on college students even a year later.     

Modeling growth in boys' aggressive behavior across elementary school: links to later criminal involvement, conduct disorder, and antisocial personality disorder

The present study used general growth mixture modeling to identify pathways of antisocial behavior development within an epidemiological sample of urban, primarily African American boys. Teacher-rated aggression, measured longitudinally from 1st to 7th grade, was used to define growth trajectories. Three high-risk trajectories (chronic high, moderate, and increasing aggression) and one low-risk trajectory (stable low aggression) were found. Boys with chronic high and increasing trajectories were at increased risk for conduct disorder, juvenile and adult arrest, and antisocial personality disorder. Concentration problems were highest among boys with a chronic high trajectory and also differentiated boys with increasing aggression from boys with stable low aggression. Peer rejection was highest among boys with chronic high aggression. Interventions with boys with distinct patterns of aggression are discussed.     

The effects of nutritional supplements on the symptoms of fibromyalgia and chronic fatigue syndrome

This article reports the results of a within-subject design. Fifty subjects with a physician diagnosis of fibromyalgia (FM) and/or chronic fatigue syndrome (CFS) were interviewed using a structured interview form. Each subject was interviewed initially, and again nine months later (follow-up). Subjects had, on their own, consumed nutritional supplements including freeze-dried aloe vera gel extract; a combination of freeze-dried aloe vera gel extract and additional plant-derived saccharides; freeze-dried fruits and vegetables in combination with the saccharides; and a formulation of dioscorea complex containing the saccharides and a vitamin/mineral complex. With medical treatments, approximately 25 percent of FM patients improved, but the beneficial effects of medical treatment rarely persist more than a few months. All subjects in this study had received some form of medical treatment prior to taking the nutritional supplements, but none with enduring success. Nutritional supplements resulted in a remarkable reduction in initial symptom severity, with continued improvement in the period between initial assessment and the follow-up. Further research is needed to verify these results, specifically crossover designs in well-defined populations.     

Men's reactions to hypothetical female sexual advances: A beauty bias in response to sexual coercion

The study investigated 277 college men's reactions to a vignette in which they were to imagine receiving an uninvited sexual advance from a casual female acquaintance. Subjects were predominantly middle-class Caucasian students. The vignette varied in the degree of coercion used (low — touch, moderate — push, high — threat, and very high — weapon). For each coercion level, the initiator was described as either very attractive or very unattractive. Subjects rated acceptability of the act, feelings of being pleased, violated, and negatively affected by the incident, and indicated if they would consent to further sexual activity. Results showed that men had significantly more negative reactions to advances that employed high and very high levels of force as compared to low and moderate levels. A beauty bias was found in that men had more positive (or less negative) reactions to the actions of an attractive vs. an unattractive initiator. Men had generally positive reactions to the sexual advance of an attractive woman who used low or moderate levels of coercion. Reactions to all other vignette situations were predominantly negative. As a model for future research, it is proposed that male and female reactions to sexual coercion can be predicted by levels of violation of sexual standards, force used, initiator sexual desirability, and romantic relationship with the initiator.     

Defensive behaviors in rats following septal and septal--amygdala lesions

Rats with anterior septal lesions showed a pattern of consistent enhancement of defensive behaviors normally elicited by threatening conspecifics, with no enhancement of attack or general reactivity. Further division of this group indicated that damage to sites anterior and ventral to the septal area, sites previously implicated in the "septal syndrome," produces maximal effect on these behaviors. When amygdala lesions are combined with septal damage this enhanced defensive responding is almost completely eliminated. These results were interpreted as indicating that the septal syndrome represents hyperdefensiveness to conspecific threat stimuli rather than aggression or increased general reactivity, and that amygdaloid mechanisms are also involved in the regulation of conspecific defensive behaviors.     

Contextes et variation trans-situationnelle des concepts

Les trois expériences présentées ont pour objectif de tester l'effet de divers contextes sur l'accès initial aux propriétés dominantes et secondaires de concepts de catégories naturelles. Les résultats indiquent l'existence d'un effet facilitateur du contexte, pour peu qu'il soit suffisamment contraignant du point de vue de la richesse sémantique, et ceci dans des temps qui garantissent l'implication de processus automatiques. Cette dernière interprétation est par ailleurs confirmée par l'absence constante d'inhibition. La dernière expérience infirme de plus l'hypothèse d'une facilitation intralexicale entre contexte et cible et confirme que c'est bien la construction sémantique élaborée par le sujet qui facilite l'accès à certaines propriétés spécifiquement pertinentes des concepts-amorces.
