Developmental Approaches to Artistic Giftedness

Two studies done from constructivist perspectives were considered for their complementarity in understanding the development of gifted young artists. Study 1 used Case's (1992) neo-Piagetian theory as a framework and investigated the developmental progression in ability to represent spatial relations in children aged 4,6,8, and I0 years. Children identified as gifted demonstrated some advancement in their use of perspective but were distinguished primarily by their elaborate and novel representations of space. An age-related progression in acquisition of ability to render perspective supports a general factor in development, whereas abilities unique to the artistic domain support the relevance of including domain-specific characteristics in developmental models of giftedness. Study 2 was done primarily from a structuralist perspective but also incorporated a postformal perspective on the problem-finding and problem-solving behaviors of young artists aged I3 to 18 years. There was support for age-related domain-general aspects of thought with discipline-specific skills in making multiple comparisons in proportional relations and coordinating multiple perspectives. This finding may be an extension of young children's intrastage elaboration of the spatial structures available to them.     

Impact of alcohol on sexual decision making: Intentions to have unprotected sex

The impact of alcohol on intentions to have sex with a new partner and the antecedents of intentions were investigated in three studies (N = 139, 60, and 218, respectively). In all three studies, respondents were intoxicated or not intoxicated with alcohol and completed measures based on the Theory of Planned Behaviour in relation to having sex whilst imagining him- or her-self in the scenario. The scenario described unprotected sex between two individuals not in an existing relationship. Consistently across studies, intoxication had a significant effect on intentions for men but not for women. Also consistently across studies, affective attitudes were significantly stronger determinants of intentions for women than for men. Alcohol intoxication consistently moderated the impact of affective attitudes on intentions in women but not men, with greater intoxication associated with stronger impacts (Studies 1, 2, and 3). Implications for understanding the impacts of alcohol intoxication on sexual decision making in men and women are discussed.     

A comparison of general and work-specific measures of core self-evaluations

During the past decade, considerable research attention has been given to core self-evaluations (CSEs). Although this research has found that CSE is related to several important work-related outcomes (e.g., job satisfaction, job performance), we believe that researchers’ reliance on general rather than work-specific CSE has resulted in underestimates of the importance of CSE. Based on the literature on frame-of-reference effects in personality assessment, we predict that work-related CSE will yield stronger relationships with work-related criteria than general CSE will and that work-specific CSE will be related to work-specific criteria after general CSE has been controlled. Using two independent samples, we found that when compared with general CSE, work-specific CSE generally failed to yield significantly stronger zero-order relationships with work-related criteria. However, we found several instances in which work-specific CSE predicted incremental variance in work-related criteria after the effects of general CSE were controlled.     

ABOLISHING AND ESTABLISHING OPERATION ANALYSES OF SOCIAL ATTENTION AS POSITIVE REINFORCEMENT FOR PROBLEM BEHAVIOR

Three participants whose problem behavior was maintained by contingent attention were exposed to 45‐min presessions in which attention was withheld, provided on a fixed‐time (FT) 15‐s schedule, or provided on an FT 120‐s schedule. Following each presession, participants were then tested in a 15‐min session similar to the social attention condition of an analogue functional analysis. The results showed establishing operation conditions increased problem behavior during tests and that abolishing operation conditions decreased problem behavior during tests.     

Color,context, and compositionality

Color adjectives have played a central role in work on language typology and variation, but there has been relatively little investigation of their meanings by researchers in formal semantics. This is surprising given the fact that color terms have been at the center of debates in the philosophy of language over foundational questions, in particular whether the idea of a compositional, truth-conditional theory of natural language semantics is even coherent. The challenge presented by color terms is articulated in detail in the work of Charles Travis. Travis argues that structurally isomorphic sentences containing color adjectives can shift truth value from context to context depending on how they are used and in the absence of effects of vagueness or ambiguity/polysemy, and concludes that a deterministic mapping from structures to truth conditions is impossible. The goal of this paper is to provide a linguistic perspective on this issue, which we believe defuses Travis’ challenge. We provide empirical arguments that color adjectives are in fact ambiguous between gradable and nongradable interpretations, and that this simple ambiguity, together with independently motivated options concerning scalar dimension within the gradable reading accounts for the Travis facts in a simpler, more constrained, and thus ultimately more successful fashion than recent contextualist analyses such as those in Szabó (Perspectives on semantics, pragmatics and discourse: A festschrift for Ferenc Kiefer, 2001) or Rothschild and Segal (Mind Lang, 2009).     

Dynamic states in working memory modulate guidance of visual attention: Evidence from an n-back paradigm

Items held in working memory (WM) can automatically bias attention when they reappear in visual displays. Recent evidence, however, suggests that WM biases of attention may be reduced under certain conditions, for example with increasing memory load. We employed a dual task paradigm to investigate how WM biases are affected by dynamic updating of memory contents. 1-back and 2-back versions of a memory task with colour stimuli were interrupted at intervals by an unrelated visual search task. Reappearance in the search display of the item that was currently active in WM guided attention, while suppressed or inactive items did not. We conclude that the rapid updating of memory contents facilitates the shifting of memory representations into different activity states on a moment-to-moment basis. The finding is consistent with models that propose that only one item can be “active” in WM at any one time to guide attention.     

Test-Retest Properties of the Least Preferred Co-worker (LPC) Score

The test-retest properties of the Least Preferred Co-Worker (LPC) scale and two subscales were examined under two conditions: (a) a naive condition, in which respondents were uninformed as to the meaning of the scale and (b) an informed condition, in which the scale was explained to respondents between administrations. The results support the hypothesis that the test-retest stability of the total LPC score would decrease significantly when respondents understood the scale. The stability of the interpersonal subscale exhibited a decrease similar to that of the total scale score, whereas the stability of the task subscale remained constant even when the scale was explained.
