Maladaptive conflict monitoring as evidence for executive dysfunction in children with chromosome 22q11.2 deletion syndrome

Using an adaptation of the Attentional Networks Test, we investigated aspects of executive control in children with chromosome 22q11.2 deletion syndrome (DS22q11.2), a common but not well understood disorder that produces non-verbal cognitive deficits and a marked incidence of psychopathology. The data revealed that children with DS22q11.2 demonstrated greater difficulty than controls in locating and processing target items in the presence of distracters. Importantly, children with DS22q11.2 showed a deficit in the ability to monitor and adapt to stimulus conflict. These data provide evidence of inadequate conflict adaptation in children with DS22q11.2, a problem that is also present in schizophrenia. The findings of specific executive dysfunction in this group may provide a linkage between particular genetic abnormalities and the development of psychopathology.     

Acceptance of cosmetic surgery: scale development and validation

We conducted a set of four studies with a total of 1288 adult and undergraduate women and men to develop the Acceptance of Cosmetic Surgery Scale. These studies provide evidence of this scale's reliability, as well as convergent and discriminant validity. Initial explorations using this 15-item scale indicate that acceptance of cosmetic surgery is negatively related to satisfaction with physical appearance and positively related to attitudes about make-up use. The acceptance of cosmetic surgery may be more related to fears about becoming unattractive than to hopes of becoming more attractive. Cosmetic surgery attitudes were positively related to age for women but not for men. The study's limitations and implications are discussed.     

Relation of academic support from parents, teachers, and peers to Hong Kong adolescents' academic achievement: the mediating role of academic engagement

The author tested a model hypothesizing that students' self-perceived academic support (from parents, teachers, and peers) is related to their achievement directly and indirectly through their own perceived academic engagement. The participants were 270 adolescents (M age = 15.41 years, range = 14-20 years) from 3 grade levels (Forms 3-5, equivalent to Grades 9-11 in the United States) in a Hong Kong secondary school. The school principal and teachers helped to collect data based on these adolescents' responses to a self-report questionnaire, consisting of a demographic profile and 4 scales assessing their self-perceptions of the extent of parental, teacher, and peer support, and their own academic engagement. Academic achievement was measured by self-reported grades in math, English, and Chinese. Structural equation modeling analyses revealed that adolescents' perceived parental, teacher, and peer support were all indirectly related to their academic achievement mediated by their own perceived academic engagement. The strength of the relationships, however, varied by support system, with perceived teacher support to achievement being the strongest, followed closely by perceived parental support, and then perceived peer support. In addition, both perceived parental support and perceived teacher support were directly related to academic achievement. However, perceived teacher support made the most total (direct and indirect) contribution to student achievement. Perceived peer support had the smallest, nonetheless significant, indirect relationship to academic achievement. However, the negative, direct influence of perceived peer support canceled out its positive, indirect influence on academic achievement.     

Conceptualizing and Measuring Historical Trauma Among American Indian People

This article reports on the development of two measures relating to historical trauma among American Indian people: The Historical Loss Scale and The Historical Loss Associated Symptoms Scale. Measurement characteristics including frequencies, internal reliability, and confirmatory factor analyses were calculated based on 143 American Indian adult parents of children aged 10 through 12 years who are part of an ongoing longitudinal study of American Indian families in the upper Midwest. Results indicate both scales have high internal reliability. Frequencies indicate that the current generation of American Indian adults have frequent thoughts pertaining to historical losses and that they associate these losses with negative feelings. Two factors of the Historical Loss Associated Symptoms Scale indicate one anxiety/depression component and one anger/avoidance component. The results are discussed in terms of future research and theory pertaining to historical trauma among American Indian people.     

Suicidal behavior among inpatients with schizophrenia and mood disorders in Chengdu, China

This study evaluated the characteristics of suicidal behavior (suicide attempt or suicidal ideation) among 230 consecutively admitted inpatients with schizophrenia and mood disorders in a university hospital in China. The rate of lifetime suicidal behavior was found to be significantly higher in patients with mood disorders (62.4%) than in patients with schizophrenia (38.6%). The rate of suicidal behavior was significantly higher in patients with major depressive disorder (86.8%) than those with bipolar disorders (42.6%). Patients with schizophrenia attempted suicide for the first time earlier in life than the patients with mood disorders. Mood disorder patients, especially those with major depressive disorder, had more and more serious suicide attempts than the patients with schizophrenia.

Auditory-oral matching behavior in newborns

Twenty-five newborn infants were tested for auditory-oral matching behavior when presented with the consonant sound /m/ and the vowel sound /a/ - a precursor behavior to vocal imitation. Auditory-oral matching behavior by the infant was operationally defined as showing the mouth movement appropriate for producing the model sound just heard (mouth opening for /a/ and mouth clutching for /m/), even when the infant produced no sound herself. With this new dependent measure, the current study is the first to show matching behavior to consonant sounds in newborns: infants showed significantly more instances of mouth opening after /a/ models than after /m/ models, and more instances of mouth clutching after /m/ models than after /a/ models. The results are discussed in the context of theories of active intermodal mapping and innate releasing mechanisms.     

Effects of the periodic administration of odor or vibration on a 3-hr. vigilance task

The present study examined performance during 3 hr. of simulated sentry duty with and without the intermittent administration of low-level sensory stimuli (odor or vibration). For odor and control conditions, target-detection latency increased steadily over the course of the 3-hr. session. Administration of a tactile stimulus reduced the increase in detection latency compared to that found in odor and control conditions. For all conditions, there were no significant differences in target-detection frequency, shot accuracy, or friend-foe discrimination. Across all conditions, restlessness (motor activity) increased significantly the first hour and remained elevated for the rest of the session. Subjective measures of workload (NASA-TLX) indicated that the 3-hr. task rated high on physical demand, mental demand, frustration, and overall workload. These findings suggest that the intermittent delivery of a clearly detectable tactile stimulus can reduce reaction-time decrements that occur as time on task increases.     

语篇理解中背景信息的激活: 情景限制的共振过程

该研究采用双人物线索语篇材料,对语篇理解中背景信息激活过程的共振模型与剧景模型进行检验。实验一发现,如果主角和配角一直同时在故事情景中成为主线索,则目标句中主角的行为可以激活那些经过屏蔽的、与这一行为相关的配角特征。在实验二中,配角只是在特征描述段落中出现,而后通过适当的描述使其在故事情景中消失,使主角成为故事的主线索,结果发现,此时目标句中主角的行为并不会激活经过屏蔽的配角的特征描述。这些结果表明,背景信息的激活虽然具有共振的特点,但共振并不是无范围限制的,而是一种情景限制下的共振。     

Associations in the course of personality disorders and Axis I disorders over time

In this study, the authors examined time-varying associations between schizotypal (STPD), borderline (BPD), avoidant (AVPD), or obsessive-compulsive (OCPD) personality disorders and co-occurring Axis I disorders in 544 adult participants from the Collaborative Longitudinal Personality Disorders Study. The authors tested predictions of specific longitudinal associations derived from a model of crosscutting psychobiological dimensions (L. J. Siever & K. L. Davis, 1991) with participants with the relevant Axis I disorders. The authors assessed participants at baseline and at 6-, 12-, and 24-month follow-up evaluations. BPD showed significant longitudinal associations with major depressive disorder and posttraumatic stress disorder. AVPD was significantly associated with anxiety disorders (specifically social phobia and obsessive-compulsive disorder). Two of the four personality disorders under examination (STPD and OCPD) showed little or no association with Axis I disorders.
