Factors of the psychopathic personality inventory: criterion-related validity and relationship to the BIS/BAS and five-factor models of personality

Psychopathy is a personality disorder that includes interpersonal-affective and antisocial deviance features. The Psychopathic Personality Inventory (PPI) contains two underlying factors (fearless dominance and impulsive antisociality) that may differentially tap these two sets of features. In a mixed-gender sample of undergraduates and prisoners, we found that PPI fearless dominance was related to low Behavioral Inhibition System activity, high Behavioral Activation System (BAS) activity, expert prototype psychopathy scores, and primary psychopathy. Impulsive antisociality was related to high BAS activity and all psychopathy measures. High Extraversion and Openness and low Neuroticism and Agreeableness predicted fearless dominance, whereas high Neuroticism and low Agreeableness and Conscientiousness predicted impulsive antisociality. Although low levels of Agreeableness predicted both PPI factors, their differential relations with other five-factor model traits highlight differences in the way psychopathy manifests itself. Consistent with movements toward assessing personality disorder using the five-factor model, the authors report regression-based equations for the clinical assessment of these psychopathy dimensions using the NEO Personality Inventory-Revised (NEO-PI-R).     

Detecting changes in simulated events II: Using variations of momentary time‐sampling to measure changes in duration events

The extent to which a greater proportion of small behavior changes could be detected with momentary time‐sampling (MTS) was evaluated by (a) combining various interval sizes of partial‐interval recording (PIR) with 20 s, 30 s, 1 min MTS and (b) using variable interval sizes of MTS that were based on means of 20 s and 1 min. For each targeted percentage, low, moderate, and high inter‐response times (IRTs) to event‐run ratios were compared with reversal designs to determine whether sensitivity increased with either variation of MTS. The results showed that (a) combinations of 30 s and 1 min MTS/PIR yielded increased sensitivity over MTS alone; however, the increased sensitivity was offset by an increased probability of generating false positives and (b) variable‐interval MTS produced comparable sensitivity to fixed‐interval MTS. Thus, none of the methods increased detection of small behavior changes (decreased false negatives) without also increasing false positives. Copyright © 2009 John Wiley & Sons, Ltd.     

An exploratory field experiment of the effect of subconscious and conscious goals on employee performance

The effect of both a primed and a conscious goal on performance in the workplace was investigated. The primed goal was pilot tested. People on their way to work (n = 52) shown a photo of a woman winning a race performed better on a brainstorming task within a 2-min time period than people in the control group. A laboratory experiment (n = 71) revealed that this primed goal significantly increased the participants’ subconscious need for achievement, as measured by a projective test, relative to those in the control group. A 2 (primed goal vs. control group) × 2 (conscious goal vs. do best goal) factorial design involving call center employees (n = 81) revealed a main effect for this primed goal, as well as a main effect for a conscious goal for money solicited from donors.     

Cross-linguistic relations between quantifiers and numerals in language acquisition: Evidence from Japanese

A study of 104 Japanese-speaking 2- to 5-year-olds tested the relation between numeral and quantifier acquisition. A first study assessed Japanese children’s comprehension of quantifiers, numerals, and classifiers. Relative to English-speaking counterparts, Japanese children were delayed in numeral comprehension at 2 years of age but showed no difference at 3 and 4 years of age. Also, Japanese 2-year-olds had better comprehension of quantifiers, indicating that their delay was specific to numerals. A second study examined the speech of Japanese and English caregivers to explore the syntactic cues that might affect integer acquisition. Quantifiers and numerals occurred in similar syntactic positions and overlapped to a greater degree in English than in Japanese. Also, Japanese nouns were often dropped, and both quantifiers and numerals exhibited variable positions relative to the nouns they modified. We conclude that syntactic cues in English facilitate bootstrapping numeral meanings from quantifier meanings and that such cues are weaker in classifier languages such as Japanese.     

Expanding the Affective and Normative Components of the Theory of Planned Behavior: A Meta‐Analysis of Anticipated Affect and Moral Norms

Meta‐analysis was used to determine the predictive validity of anticipated affect and moral norms in the theory of planned behavior (TPB; Ajzen, 1991 ). Medium‐to‐large sample‐weighted average correlations were obtained. Anticipated affect and moral norms increased the variance explained in intentions by 5% and 3%, respectively, controlling for TPB variables. Intention mediated the influence of both variables on behavior. Moderator analyses showed that younger samples and behaviors with a moral dimension were associated with stronger moral‐norm/intention relations, and anticipated regret was associated with a stronger anticipated‐affect/intention relation. The implications of the findings for the TPB are discussed.     

The spacing effect in intentional and incidental free recall by children and adults: Limits on the automaticity hypothesis

Preschoolers, elementary school children, and college students exhibited a spacing effect in the free recall of pictures when learning was intentional. When learning was incidental and a shallow processing task requiring little semantic processing was used during list presentation, young adults still exhibited a spacing effect, but children consistently failed to do so. Children, however, did manifest a spacing effect in incidental learning when an elaborate semantic processing task was used. These results limit the hypothesis that the spacing effect in free recall occurs automatically and constrain theoretical accounts of why the spacing between repetitions affects recall performance.     

Incremental and predictive utility of formative assessment methods of reading comprehension

Formative assessment measures are commonly used in schools to assess reading and to design instruction accordingly. The purpose of this research was to investigate the incremental and concurrent validity of formative assessment measures of reading comprehension. It was hypothesized that formative measures of reading comprehension would contribute more to our understanding of students' overall reading abilities than simply oral reading fluency (ORF). It was also hypothesized that measures could be modeled in a meaningful way to explain student performance on criterion measures of academic competence. Four formative measures of reading comprehension – maze (MZ), retell fluency (RTF), written retell (WRT), and sentence verification technique (SVT) – were used to measure unique aspects of reading comprehension through production-type responses. Results suggested that reading comprehension measures, when combined with ORF, added to the total variance associated with reading ability and were reliable indicators of student performance on a high stakes criterion-referenced assessment of grade-level literacy.     

Probabilistically Valid Inference of Covariation From a Single x,y Observation When Univariate Characteristics Are Known

Participants were asked to draw inferences about correlation from single x,y observations. In Experiment 1 statistically sophisticated participants were given the univariate characteristics of distributions of x and y and asked to infer whether a single x, y observation came from a correlated or an uncorrelated population. In Experiment 2, students with a variety of statistical backgrounds assigned posterior probabilities to five possible populations based on single x, y observations, again given knowledge of the univariate statistics. In Experiment 3, statistically naïve participants were given a problem analogous to that given in Experiment 1, framed verbally. Experiment 4 replicated Experiment 3 but added an "impossible to determine" response option. Models that rely on computing sample correlations make no predictions about these investigations. From a Bayesian perspective, participants' inferences in all four experiments tended to make probabilistically valid inferences as long as the single datum was directional. The results are discussed in light of the Brunswikian notion of vicarious functioning.     

Teaching a simple meal preparation skill to adults with moderate and severe mental retardation using video modeling

We evaluated whether adults with mental retardation in the moderate or severe range would acquire simple meal preparation skills via video modeling. Training was conducted in the kitchen of the participants' day treatment setting. The intervention consisted of (i) watching a video of an adult with a developmental disability making a peanut butter and jelly sandwich and (ii) receiving verbal praise for each step of the task that was performed correctly. All three participants mastered the task and demonstrated generalization across settings. All three participants also demonstrated maintenance of the skill one month following mastery.
