Development of the appearance-reality distinction

Young children can express conceptual difficulties with the appearance-reality distinction in two different ways: (1) by incorrectly reporting appearance when asked to report reality (“phenomenism”); (2) by incorrectly reporting reality when asked to report appearance (“intellectual realism”). Although both phenomenism errors and intellectual realism errors have been observed in previous studies of young children's cognition, the two have not been seen as conceptually related and only the former errors have been taken as a symptom of difficulties with the appearance-reality distinction. Three experiments investigated 3- to 5-year-old children's ability to distinguish between and correctly identify real versus apparent object properties (color, size, and shape), object identities, object presence-absence, and action identities. Even the 3-year-olds appeared to have some ability to make correct appearance-reality discriminations and this ability increased with age. Errors were frequent, however, and almost all children who erred made both kinds. Phenomenism errors predominated on tasks where the appearance versus reality of the three object properties were in question; intellectual realism errors predominated on the other three types of tasks. Possible reasons for this curious error pattern were advanced. It was also suggested that young children's problems with the appearance-reality distinction may be partly due to a specific metacognitive limitation, namely, a difficulty in analyzing the nature and source of their own mental representations.     

Within-Session Patterns of Pigeons'' General Activity

The study investigates the idea that within-session changes in responding are produced by arousal and satiation. General activity, measured by the displacement of floor panels, was used as an index of these variables. In Experiment 1, pigeons pecked a key on a simple variable-interval schedule and general activity was also recorded. In Experiment 2, pigeons received response-independent reinforcers. In Experiment 3, the pigeons' general activity was reinforced on a variable-interval schedule. Although significant within-session changes in operant key pecking were observed in Experiment 1, within-session changes in general activity were seldom observed in either Experiment 1 or Experiment 2. Significant within-session changes in general activity were observed in Experiment 3, when activity was the operant. The present results can potentially be explained by arousal and satiation. However, the predictive power of this explanation is severely limited. Regardless of whether one accepts arousal and satiation as the theoretical explanation for within-session changes in responding, the present results suggest that aspects of the response–reinforcer relation may determine the within-session pattern of responding.     

A test of object permanence in a new-world monkey species,cotton top tamarins (<Emphasis Type="Italic">Saguinus oedipus</Emphasis>)

Cotton top tamarins were tested in visible and invisible displacement tasks in a method similar to that used elsewhere to test squirrel monkeys and orangutans. All subjects performed at levels significantly above chance on visible (n=8) and invisible (n=7) displacements, wherein the tasks included tests of the perseverance error, tests of memory in double and triple displacements, and "catch" trials that tested for the use of the experimenter's hand as a cue for the correct cup. Performance on all nine tasks was significantly higher than chance level selection of cups, and tasks using visible displacements generated more accurate performance than tasks using invisible displacements. Performance was not accounted for by a practice effect based on exposure to successive tasks. Results suggest that tamarins possess stage 6 object permanence capabilities, and that in a situation involving brief exposure to tasks and foraging opportunities, tracking objects' movements and responding more flexibly are abilities expressed readily by the tamarins.

Self-Efficacy for Affect Regulation as a Predictor of Future Life Satisfaction and Moderator of the Negative Affect—Life Satisfaction Relationship

Life satisfaction is an important index of mental health and also predicts other important outcomes such as longevity and decreased mortality. Negative affect has a unique inverse relationship with life satisfaction across the life span. Therefore, determining psychological factors that uniquely predict future life satisfaction and that reduce the trait negative affect—life satisfaction relationship is theoretically and clinically important. In light of recent evidence from long-term longitudinal studies that self-efficacy for regulation of negative emotions (SERN) predicts higher future life satisfaction, as well as evidence from a cross-sectional study that a subtype of SERN—self-efficacy for regulating anger—buffers the relationship between trait negative affect and life satisfaction, we tested whether SERN and subtypes of SERN predicted higher life satisfaction and buffered the negative affect—life satisfaction relationship longitudinally over short time periods. After controlling for time 1 life satisfaction, higher time 1 self-efficacy for regulating despondency and distress (SEDes) predicted higher future life satisfaction over average time periods of 17 days (N = 127), 32 days (N = 83), and 41 days (N = 65) among college students. However, in post hoc exploratory regressions that included self-efficacy for experience and expression of positive emotions (SEPos), SEDes predicted higher time 2 life satisfaction, but only SEPos uniquely predicted higher time 3 and time 4 life satisfaction.     

Reading aloud begins when the computation of phonology is complete

Naming latency experiments in which monosyllabic items are read aloud are based on the assumption that the vocal response is not initiated until the phonology of the entire syllable has been computed. Recently, this assumption has been challenged by A. H. Kawamoto, C. T. Kello, R. Jones, and K. Bame (1998), who argued instead that the reading-aloud response begins as soon as the initial phoneme is computed. This view would be refuted by evidence of anticipatory coarticulation effects on the initial phoneme due to the nature of the following vowel in the speeded reading-aloud task. The authors provide such evidence.     

Seeking one’s heading through eye movements

A study of eye movements during simulated travel toward a grove of four stationary trees revealed that observers looked most at pairs of trees that converged or decelerated apart. Such pairs specify that one’s direction of travel, calledheading, is to the outside of the near member of the pair. Observers looked at these trees more than those that accelerated apart; such pairs do not offer trustworthy heading information. Observers also looked at gaps between trees less often when they converged or diverged apart, and heading can never be between such pairs. Heading responses were in accord with eye movements. In general, if observers responded accurately, they had looked at trees that converged or decelerated apart; if they were inaccurate, they had not. Results support the notion that observers seek out their heading through eye movements, saccading to and fixating on the most informative locations in the field of view.     

Human navigation in nested environments

Navigation in humans and many other animals relies on spatial representations of their environments. Three experiments examined how humans maintain sense of orientation between nested environments. Subjects can acquire new spatial representations easily without integrating them into their existing spatial knowledge system. While navigating between nested environments, subjects seemed to constantly switch between the currently processed environment by reorienting to approaching environments and losing track of old environments at given spatial regions. These results suggest that spatial updating in naturalistic, nested environments does not occur for all environments at the same time. Implications for the hierarchical theory of spatial representations and the path integration theory of navigation are discussed.     

Metatraits and assessment of attributional style

Some personality trait dimensions may not be equally applicable to all people. The degree of applicability of a given trait, or traitedness, is conceptually distinct from trait level. In this study, 3 ways of assessing traitedness--interitem variance (R. F. Baumeister & D. M. Tice, 1988), scalability (K. Lanning, 1988), and construct similarity (W. F. Chaplin, 1991)--were applied to attributional style. A nonclinical sample (N = 123) completed measures of attributional style and depressive symptoms. In a series of multiple regression analyses, none of the traitedness indicators significantly moderated the relation of attributional style with depressive symptoms. The authors discuss several methodological and conceptual explanations for these null results.     

New Migrants in Residential Aged Care: Managing Diversity in Not-for-Profit Organisations

This paper draws on qualitative interviews with migrant Indo-Asian and African personal care workers and registered and enrolled nurses employed by two not-for-profit residential aged care organisations in Australia: AnglicareSA and Resthaven Inc. The paper examines the way these culturally and linguistically diverse staff talk about the safe organisational environment provided by their employers, while in the wider Australian environment, low levels of hostility towards migrants and refugees are a constant cultural force. We demonstrate the impact of these organisations’ foundational ethics and values that influence how human resource diversity management strategies impact on the quality care provided to residents. We argue that this ethic and these human resource strategies act as conduits for culturally and linguistically diverse (CALD) staff to integrate into the workforce and as a mechanism in assisting new migrants to transition into the wider Australian society, while at the same time enriching the care of the older persons.
