The inter-domain among personality and cognition variables in people who commit murder

The inter-domain among personality (MMPI) and cognition (intelligence) variables in a sample of 137 males charged with first degree or capital murder was examined through canonical analysis. Race was included as a control variable. Two significant canonical correlations were found which contribute to an understanding of the relationship between personality and cognition in violent people. These variates were identified as Problem-solving Focus and Introspective Self-focus. Results also suggest that these inter-domain variates explain the relationship between personality and cognition variables to a greater degree for black murderers than for white murderers.     

On the locus of the semantic satiation effect: Evidence from event-related brain potentials

The present study sought to determine whether semantic satiation is merely a by-product of adaptation or satiation of upstream, nonsemantic perceptual processes or whether the effect can have a locus in semantic memory. This was done by measuring event-related brain potentials (ERPs) in a semantic word-detection task involving multiple presentations of primes and critical related and unrelated words in three experiments involving visual (Experiment 1) and auditory (Experiments 2A and 2B) stimuli. Primes varied in their type case (Experiment 1) or pitch (Experiment 2B) in order to discourage sensory adaptation. Prime satiation and relatedness of the primes to the critical word had interacting effects on ERP amplitude to critical words, particularly within the time-window of the N400 component. Because numerous studies have indicated a role for the N400 in semantic processing, modulation of the N400 relatedness effect by prime satiation (with little or no contribution from perceptual adaptation) suggests that semantic memory can be directly satiated, rather than the cost to semantic processing necessarily resulting from impoverishment of perceptual inputs.     

Multicultural Counseling Competencies: An Exploratory Factor Analysis

The author examined the underlying factors of the Association of Multicultural Counseling and Development's (AMCD) Multicultural Competencies. One hundred fifty‐one professional counselors who are members of the American Counseling Association responded to a survey that included items reflecting AMCD's multicultural competencies and Explanatory Statements. An exploratory factor analysis revealed 5 multicultural competencies factors: Awareness, Knowledge, Definitions of Terms, Racial Identity Development, and Skills.     

Forging a Collaborative Relationship Between the Black Church and the Counseling Profession

In the field of counseling, there has been a growing awareness of the important role the Black church plays in African American communities. Although counseling professionals have begun recognizing the influence the Black church has in the lives of African Americans, there seems to be little information on how counselors can collaborate with African American congregations to meet the mental health needs of African American clients. The authors examine how counselors can use the psychological and social strengths of the Black church. Strategies and implications for collaborating with this institution are also discussed.     

School Counselors as Social Capital: The Effects of High School College Counseling on College Application Rates

Using social capital theory as a framework, the authors examined data from the Educational Longitudinal Study of 2002 (Ingels, Pratt, Rogers, Siegel, & Stutts, 2004) to investigate how student contact with high school counselors about college information and other college‐related variables influence students' college application rates. In addition to some college‐related variables, the number of school counselors and student contacts were significant predictors of college application rates. Implications for school counselors and counselor training are included.     

Time travel through language: Temporal shifts rapidly decrease information accessibility during reading

The present study dissociated the immediate neural costs from the subsequent neural consequences of integrating time shifts into our mental representations of events. Event-related potentials were recorded as participants read scenarios that included words referring to short temporal shifts (e.g., after one second), moderate temporal shifts (e.g., after one hour), or long temporal shifts (e.g., after one year). These words were followed by repeated noun-phrase anaphors, which are preferred as referents for information no longer in attentional focus. The N400 was measured as an index of online conceptual integration. As the discourse unfolded, the N400 was larger for long- (e.g.,year) than for short- (e.g., second) shift words. For the anaphor, the N400 was modulated in the opposite direction. Thus, the introduction of a temporal discontinuity leads to immediate neural integration costs, as well as to decreased accessibility of earlier information.     

Is the donut in front of the car? An electrophysiological study examining spatial reference frame processing.

The process of describing an object's location relative to another object results in ambiguity. How do people handle this ambiguity? The present studies examined spatial language processing when use of different reference frames results in ambiguity. We investigated whether electrophysiological (ERP) measures of cognitive processing may elucidate underlying reference frame processing; in particular, we were interested in semantic integration. ERP results showed a larger N400, peaking between 300 and 375 ms, when the intrinsic frame was not used. Behavioural results mirrored this finding, indicating a reduced cognitive processing requirement for the intrinsic reference frame. Previous work has not definitively tied spatial reference frame processing to specific ERP components and their associated cognitive processes. Although the N400 peak seen in this data is early, additional work supports the N400 interpretation, thereby linking spatial frame processing to semantic integration. Results are discussed within the larger context of spatial reference frame processing.     

Effects of high and low dosages of methylphenidate in children with strong and sensitive nervous systems

This investigation was undertaken to explore the possible causes and consequences of the finding that attention- and learning-disordered children with sensitive (weak) nervous systems were titrated at higher dosages of methylphenidate than those with strong nervous systems. Pretreatment parent and teacher ratings of hyperkineticassociated behavior were no different for children typed as having strong or sensitive nervous systems or for those subsequently prescribed higher or lower dosages by a child psychiatrist “blind” to their type as well as condition (drug or placebo). However, those titrated at lower dosages, regardless of whether strong or sensitive, were rated as more improved than those given higher dosages. Pretreatment reaction time (RT) data suggested that sensitive types prescribed low dosages had less of a problem sustaining attention, and placebo RT data suggested that strong types titrated at low dosages had more of a problem sustaining attention. A contrast of placebo and drug RTs showed that strong types titrated at lower dosages improved more than strong types given higher dosages, whereas sensitive types given higher dosages improved more than sensitive types given lower dosages. The latter finding is thought to add support to the theory of Gray (1964), who suggested that, paradoxically, the weak nervous system needs a more intense stimulus than the strong to reach the concentration threshold.     

The time course of orthographic and phonological code activation

The present study used event-related potentials (ERPs) to examine the time course of orthographic and phonological priming in the masked priming paradigm. Participants monitored visual target words for occasional animal names, and ERPs to nonanimal critical items were recorded. These critical items were preceded by different types of primes: Orthographic priming was examined using transposed-letter (TL) primes (e.g., barin-BRAIN) and their controls (e.g., bosin-BRAIN); phonological priming was examined using pseudohomophone primes (e.g., brane-BRAIN) and their controls (e.g., brant-BRAIN). Both manipulations modulated the N250 ERP component, which is hypothesized to reflect sublexical processing during visual word recognition. Orthographic (TL) priming and phonological (pseudohomophone) priming were found to have distinct topographical distributions and different timing, with orthographic effects arising earlier than phonological effects.
