Subliminal words activate semantic categories (not automated motor responses)

Semantic priming by visually masked, unidentifiable (“subliminal”) words occurs robustly when the words appearing as masked primes have been classified earlier in practice as visible targets. It has been argued (Damian, 2001) that practice enables robust subliminal priming by automatizing learned associations between words and the specific motor responses used to classify them. Two experiments demonstrate that, instead, the associations formed in practice that underlie subliminal priming are between words and semantic categories. Visible words classified aspleasant or unpleasant in practice with one set of response key assignments functioned later as subliminal primes with appropriate valence, even when associations of keys with valences were reversed before the test. This result shows that subliminal priming involves unconscious categorization of the prime, rather than just the automatic activation of a practiced stimulus-response mapping.     

Using the implicit association test to measure age differences in implicit social cognitions

Two studies investigated the use of the Implicit Association Test (IAT; A. G. Greenwald, D. E. McGhee, & J. L. K. Schwartz, 1998) to study age differences in implicit social cognitions. Study I collected IAT (implicit) and explicit (self-report) measures of age attitudes, age identity, and self-esteem from young, young-old, and old-old participants. Study 2 collected IAT and explicit measures of attitudes toward flowers versus insects from young and old participants. Results show that the IAT provided theoretically meaningful insights into age differences in social cognitions that the explicit measures did not, supporting the value of the IAT in aging research. Results also illustrate that age-related slowing must be considered in analysis and interpretation of IAT measures.     

Should we create a niche or fall in line? Identity negotiation and small group effectiveness

A prospective study of 423 MBA students examined the interplay of identity negotiation and group functioning. The findings revealed that self-verification effects (through which group members brought others to see them as they saw themselves) heightened participants' feelings of connection to their groups (i.e., more identification and social integration and less emotional conflict) and improved group project grades on creative tasks (tasks that benefit from divergent perspectives). Appraisal effects (through which groups brought members to see themselves as the group saw them) facilitated group project grades on computational tasks (tasks that require deriving one correct answer). In addition, self-verification effects were more prevalent than appraisal effects. The authors discuss the implications of these findings for understanding the links among self-verification, self-categorization, and group outcomes.     

Development of emergent literacy and early reading skills in preschool children: evidence from a latent-variable longitudinal study

Although research has identified oral language, print knowledge, and phonological sensitivity as important emergent literacy skills for the development of reading, few studies have examined the relations between these aspects of emergent literacy or between these skills during preschool and during later reading. This study examined the joint and unique predictive significance of emergent literacy skills for both later emergent literacy skills and reading in two samples of preschoolers. Ninety-six children (mean age = 41 months, SD = 9.41) were followed from early to late preschool, and 97 children (mean age = 60 months, SD = 5.41) were followed from late preschool to kindergarten or first grade. Structural equation modeling revealed significant developmental continuity of these skills, particularly for letter knowledge and phonological sensitivity from late preschool to early grade school, both of which were the only unique predictors of decoding.     

Training parents as behavior therapists: A review

The following paper presents theoretical, empirical, and ethical rationales for the training of parents as behavior therapists for their own children. Thirty-four studies, ranging from single case studies to reports on large-scale, multi-family training programs, are critically reviewed, with primary emphasis on the nature and extent of parental involvement and responsibility, and on the level of methodological sophistication. Related papers are cited when appropriate. Further research and areas needing theoretical clarification are suggested, in relation to the future and expansion of this type of therapeutic intervention. In addition the implications of such an approach for both a “systems” model of child therapy and a prevention-oriented model of mental health services are discussed.     

Predicting dangerousness with two Millon Adolescent Clinical Inventory psychopathy scales: the importance of egocentric and callous traits

Psychopathy in youth has received increased recognition as a critical clinical construct for the evaluation and management of adolescents who have come into contact with the law (e.g., Forth, Hare, & Hart, 1990; Frick, 1998; Lynam, 1996, 1998). Although considerable attention has been devoted to the adult construct of psychopathy and its relation to recidivism, psychopathy in adolescents has been less thoroughly researched. Recently, a psychopathy scale (Murrie and Cornell Psychopathy Scale; Murrie & Cornell, 2000) was developed from items of the Millon Adolescent Clinical Inventory (MACI; Millon, 1993). This scale was found to be highly related to the Psychopathy Checklist-Revised (Hare, 1991) and was judged to have demonstrated good criterion validity. A necessary step in the validation process of any psychopathy scale is establishing its predictive validity. With this in mind, we investigated the ability of the MACI Psychopathy Scale to predict recidivism with 55 adolescent offenders 2 years after they had been evaluated at a juvenile court evaluation unit. In addition, we devised a psychopathy scale from MACI items that aligned more closely with Cooke and Michie (2001) and Frick, Bodin, and Barry's (2001) recommendations for the refinement of psychopathy and tested its predictive validity. Results indicate that both scales had predictive utility. Interpersonal and affective components of the revised scale were particularly important in the prediction of both general and violent reoffending.     

Number of older brothers and sexual orientation: new tests and the attraction/behavior distinction in two national probability samples

The extent to which number of older brothers or "fraternal birth order" predicted the 2 main components that researchers have traditionally used to conceptualize sexual orientation-that is, psychological attraction and sexual behavior-was examined in 2 recent national probability samples. In both studies, fraternal birth order predicted same-sex attraction in men, with each additional older brother increasing the odds of homosexual attraction by an average of 38%. Results also indicated that the fraternal birth order/same-sex attraction relationship in men was independent of sexual behavior, including early same-sex behavior. No sibling characteristics predicted sexual orientation in women. Results suggest experience-based theories (e.g., early same-sex play) of the fraternal birth order effect in men are unlikely to be correct.     

NEO-five factor personality traits as predictors of response to two forms of group psychotherapy

The relationships between patient personality variables and outcome for 107 psychiatric outpatients with complicated grief who completed either interpretive or supportive short-term group therapy were investigated. The personality variables were assessed prior to treatment with the NEO-Five Factor Inventory (NEO-FFI). For patients in both forms of therapy, extraversion, conscientiousness, and openness were directly associated with favorable treatment outcome. In contrast, neuroticism was inversely related to favorable outcome for patients in both forms of therapy. Agreeableness was directly related to favorable improvement in grief symptomatology for patients in interpretive therapy, but not for those in supportive therapy. The results highlight the importance of assessing patient personality in order to predict response to short-term group therapy. Possible explanations and clinical implications of these findings are discussed.     

Interference processes in monkey auditory list memory

A rhesus monkey’s memory was tested for single items and four-item lists of natural and environmental sounds. Memory items were presented from a center speaker, followed by a retention delay and then a choice response to a test sound presented simultaneously from two side speakers. Recognition of the last item of four-item lists was much poorer than that of single items at 0-, 1-, and 2-sec delays, despite there being the same temporal relations between study and test. This result showed that the first three items proactively interfered with memory of the last list item. Proactive interference dissipated after 2 sec, revealing a recency effect that eventually equaled single-item performance. Recognition of the first item of four-item lists was much poorer than single items at 20- and 30-sec delays, showing that the last three items retroactively interfered with memory of the first list item. The results point to the critical nature of interference processes in the understanding of serial position functions.
