Abusive supervision and family undermining as displaced aggression

This study focuses on factors that contribute to abusive supervision, one form of nonphysical aggression, and the results of such abuse on subordinates and their family members. Using a "kick the dog" metaphor (As Marcus-Newhall, Pedersen, Carlson, and Miller (2000) state, this is a "commonly used anecdote to illustrate displaced aggression. . .a man is berated by his boss but does not retaliate because he fears losing his job. Hours later, when he arrives home to the greeting barks of his dog he responds by kicking it," p. 670), the authors investigated whether abusive supervision may be the result of a supervisor's displeasure with his or her organization. Using a sample of 210 supervisors, their subordinates, and the subordinates' family members or partners, the authors hypothesized that supervisors' reports of psychological contract violations, moderated by hostile attribution bias, would be associated with subordinates' perceptions of abusive supervision. In turn, the authors hypothesized that abused subordinates' family members would report sustained negative affect and negative evaluations directed toward them in the home. The hypotheses were supported.     

Changing the tune: the structure of the input affects infants' use of absolute and relative pitch

Sequences of notes contain several different types of pitch cues, including both absolute and relative pitch information. What factors determine which of these cues are used when learning about tone sequences? Previous research suggests that infants tend to preferentially process absolute pitch patterns in continuous tone sequences, while other types of input elicit relative pitch use by infants. In order to ask whether the structure of the input influences infants’ choice of pitch cues, we presented learners with continuous tone streams in which absolute pitch cues were rendered uninformative by transposing the tone sequences. Under these circumstances, both infants and adults successfully tracked relative pitches in a statistical learning task. Implications for the role played by the structure of the input in the learning process are considered.     

Interaction of vision and movement via a mirror

I have noticed a striking effect that vision can have on movement: when a person makes circular motions with both hands, clockwise with the left hand, counterclockwise with the right hand, while watching the reflection of one hand in a parasagitally placed mirror, if one arm makes a vertical excursion, the other arm tends to make the same vertical excursion, but not typically if the excursing arm is viewed in plain vision. This observation may help in understanding how visual feedback via a mirror may be beneficial for rehabilitation of some patients with movement deficits secondary to certain neurologic conditions, and illustrates that the traditional division of neural processes into sensory input and motor output is somewhat arbitrary.     

Self-reported parental abuse relates to autobiographical memory style in patients with eating disorders

Previous research has shown a relationship between levels of self-reported childhood abuse and overgeneral memory style. This relationship was further clarified in patients with an eating disorder (ED). Patients and healthy controls completed a task in which they had to generate specific autobiographical memories to emotional cue words. The results showed that first, the ED group, relative to the controls, produced more first memories that were "overgeneral" and fewer first memories that were specific. Second, in the ED group, the level of self-reported parental abuse was positively correlated with the tendency to produce overgeneral memories to negative cues. This effect remained significant even after levels of depressed mood were controlled for.     

Motor and functional skills of children with developmental coordination disorder: a pilot investigation of measurement issues

This paper reports on the motor and functional outcomes of 20 children with developmental coordination disorder (DCD) aged 4-8 years consecutively referred to a pediatric physiotherapy service. Children with a Movement ABC (M-ABC) score less than the 15th percentile, and with no concurrent medical, sensory, physical, intellectual or neurological impairments, were recruited. The Motor Assessment Outcomes Model (MAOM) [Coster and Haley, Infants and Young Children 4 (1992) 11] provided the theoretical base for measurement selection, and preliminary findings at the activities and participation levels of the model are reported in this article. Children with DCD performed at the lower end of the normal range on the Peabody Developmental Motor Scales (fine motor total score) (M=85.65, SD=12.23). Performance on the Visual Motor Integration Test (VMI) standard scores was within the average range (M=96.15, SD=10.69). Videotaped observations of the children's writing and cutting indicated that 29% were left-handed and that a large proportion of all children (31%) utilized unusual pencil grasp patterns and immature prehension of scissors. Measurement at the participation level involved use of the Pictorial Scale of Perceived Competence and Social Acceptance (PCSA) and Pediatric Evaluation of Disability Inventory (PEDI). Overall, these young children rated themselves towards the more competent and accepted end of the PCSA over the dimensions of physical and cognitive competence and peer and maternal acceptance. The PEDI revealed generally average performance on social (M=49.98, SD=16.62) and mobility function (M=54.71, SD=3.99), however, self-care function was below the average range for age (M=38.01, SD=12.19). The utility of the MAOM as a framework for comprehensive measurement of functional and motor outcomes of DCD in young children is discussed.     

When cues collide: use of stress and statistical cues to word boundaries by 7- to 9-month-old infants

Prior research suggests that stress cues are particularly important for English-hearing infants' detection of word boundaries. It is unclear, though, how infants learn to attend to stress as a cue to word segmentation. This series of experiments was designed to explore infants' attention to conflicting cues at different ages. Experiment 1 replicated previous findings: When stress and statistical cues indicated different word boundaries, 9-month-old infants used syllable stress as a cue to segmentation while ignoring statistical cues. However, in Experiment 2, 7-month-old infants attended more to statistical cues than to stress cues. These results raise the possibility that infants use their statistical learning abilities to locate words in speech and use those words to discover the regular pattern of stress cues in English. Infants at different ages may deploy different segmentation strategies as a function of their current linguistic experience.     

Acquisition and automatization of a complex task: an examination of three-ball cascade juggling

The learning patterns of 3-ball cascade juggling from acquisition until automaticity were examined in 10 participants. On the basis of outcome measures derived from 26 practice sessions and 4 periodic probe sessions, the authors differentiated participants into 3 distinct learning types: a proficient group, an emerging group, and a single late learner. The proficient group was distinguished by how rapidly they learned and automatized performance. Most interesting, an inverse response cost (i.e., performance boost) on the secondary task was found in the majority of proficient group members during the dual-task condition. The present results are discussed in relation to the P. L. Ackerman model (1987, 1988) of complex skill acquisition as is the significance of the inverse response cost finding.     

Feeling safe at work: Development and validation of the Psychological Safety Inventory

Psychological safety, defined as perceptions that an individual within a team is supported and feels safe to take interpersonal risks, voice opinions, and share ideas, is vital for organizational effectiveness. However, there is no consensus on how workplace psychological safety should be measured. We developed the Psychological Safety Inventory (PSI) in response to organizational needs to accurately assess psychological safety. A 70-item version of the PSI was administered to 497 employees from Canada, the United States, and the United Kingdom. Based on factor analytic findings, we reduced the preliminary PSI to a 30-item, five-factor scale. The PSI showed high reliability and correlated as anticipated with convergent measures. Overall, the PSI is a valid and reliable measure of workplace psychological safety.     

Availability,Similarity, and Gender as Determinants of Adolescent Peer Acceptance1

Attributes of accepted classmates were investigated as a function of (a) respondent-target similarity, (b) availability of desirable peers, (c) gender of respondent and accepted peers, and (d) level of intimacy of the social contact. It was assumed that availability would play a greater role than was previously recognized, in determining attributes of accepted peers in casual as well as intimate contacts, and same-gender and opposite-gender acceptance of males and females would be affected differentially by availability and similarity. Seven hundred and fitly-five 6th, 7th. and 8th grade male and female students indicated their readiness to engage in closer or more casual contacts with each of their classmates, using the Interpersonal Relationship Assessment Technique. It was found that in more superficial relations attributes of accepted peers tended to reflect availability of desirable peers (mean level of desirable student attributes in class), but not respondent-peer similarity; whereas readiness to maintain more intimate contacts with peers was significantly associated with similarity between respondent and accepted peers, as well as availability of desirable peers. It was found further that availability and similarity play different roles in determining acceptance of same-gender or opposite-gender peers by boys and by girls. These results were replicated over four levels of intimacy and four different student attributes.     

INCIDENTAL LANGUAGE LEARNING:

Abstract —Two experiments investigated the performance of first-grade children and adults on an incidental language-learning task. Learning entailed word segmentation from continuous speech, an initial and crucial component of language acquisition. Subjects were briefly exposed to an unsegmented artificial language, presented auditorily, in which the only cues to word boundaries were the transitional probabilities between syllables. Subjects were not told that they were listening to a language, or even to listen at all; rather, they were engaged in a cover task of creating computer illustrations. Both adults and children learned the words of the language. Moreover, the children performed as well as the adults. These data suggest that a statistical learning mechanism (transitional probability computation) is able to operate incidentally and, surprisingly, as well in children as in adults.
