Agency,Consciousness, and Executive Control

On the Causal Theory of Action (CTA), internal proper parts of an agent such as desires and intentions are causally responsible for actions. CTA has increasingly come under attack for its alleged failure to account for agency. A recent version of this criticism due to François Schroeter proposes that CTA cannot provide an adequate account of either the executive control or the autonomous control involved in full-fledged agency. Schroeter offers as an alternative a revised understanding of the proper role of consciousness in agency. In this paper we criticize Schroeter’s analysis of the type of consciousness involved in executive control and examine the way in which the conscious self allegedly intervenes in action. We argue that Schroeter’s proposal should not be preferred over recent versions of CTA.     

The absence of a shape bias in children's word learning

There is debate about whether preschool-age children interpret words as referring to kinds or to classes defined by shape similarity. The authors argue that the shape bias reported in previous studies is a task-induced artifact rather than a genuine word-learning strategy. In particular, children were forced to extend an object's novel label to one of several stand-alone, simple-shaped items, including a same-shape option from a different category and a different-shape option from the same superordinate category. Across 6 experiments, the authors found that the shape bias was eliminated (a) when the objects were more complex, (b) when they were presented in context, or (c) when children were no longer forced to choose. Moreover, children preferred the different-shape category alternatives when these were part of the same basic-level category as the target. The present experiments suggest that children seek out objects of the same kind when presented with a novel label, even if they are sometimes unable to identify the relevant kinds on their own.     

Relationships of career adaptabilities with explicit and implicit self-concepts

Career adaptability is a psychosocial construct that incorporates a set of essential resources to one's career development. The adaptability resources' relevance is even higher when it comes to former communist countries, such as Romania, where job security and stability were seen as central benefits for workers. The aim of this study was to provide a more comprehensive understanding of the stable underpinnings of career adaptabilities by exploring their relationships with aspects of the self that are driven by automatic processes and that are less affected by self-presentation biases. A sample of 359 participants completed the Career Adapt Abilities Scale (CAAS)-Romanian form, out of which a subsample of 212 participants also completed a set of scales comprising explicit and implicit measures of conscientiousness, extraversion, neuroticism, and self-esteem. Results revealed nonsignificant additive contributions of the implicit self-concept measures over what was already explained by the explicit self-concepts. The most noticeable effect resides in the significant interaction between explicit and implicit self-esteem in relation to control, confidence, and overall adaptability. These results reveal that individuals with high explicit and low implicit self-esteem perceive themselves as being the most adaptable. Notably, these results were obtained using a Romanian version of CAAS that possesses very good psychometric properties (i.e., excellent internal consistencies, the same four-factor multidimensional solution, replicated patterns of associations between CAAS and explicit self-concepts of personality).     

Behavioral variability in an evolutionary theory of behavior dynamics

McDowell’s evolutionary theory of behavior dynamics (McDowell, 2004) instantiates populations of behaviors (abstractly represented by integers) that evolve under the selection pressure of the environment in the form of positive reinforcement. Each generation gives rise to the next via low‐level Darwinian processes of selection, recombination, and mutation. The emergent patterns can be analyzed and compared to those produced by biological organisms. The purpose of this project was to explore the effects of high mutation rates on behavioral variability in environments that arranged different reinforcer rates and magnitudes. Behavioral variability increased with the rate of mutation. High reinforcer rates and magnitudes reduced these effects; low reinforcer rates and magnitudes augmented them. These results are in agreement with live‐organism research on behavioral variability. Various combinations of mutation rates, reinforcer rates, and reinforcer magnitudes produced similar high‐level outcomes (equifinality). These findings suggest that the independent variables that describe an experimental condition interact; that is, they do not influence behavior independently. These conclusions have implications for the interpretation of high levels of variability, mathematical undermatching, and the matching theory. The last part of the discussion centers on a potential biological counterpart for the rate of mutation, namely spontaneous fluctuations in the brain's default mode network.     

Dispositional Optimism and Judgments of Future Life Events: Affective States as Moderators

This research examined the relation between dispositional optimism and judgments of future life events and whether this relation is moderated by affective states. In this study the moderating role of experimentally induced affective states, using film clips (N = 259), was investigated. After filling in the questionnaire for dispositional optimism, the participants were randomly assigned in the experimental conditions in order to induce positive versus negative affective states. Finally, the participants filled in the affective states and judgments of future life events scales. The results indicated that the participants with a higher level of optimism had the tendency to judge positive events as more likely and negative events as less likely to happen in the future. We found evidence for affective states as moderators; the association between dispositional optimism and judgments of future positive events depended on experimentally induced affective states. Specifically, in positive affective state condition, the association between dispositional optimism and judgments of future positive events was weaker than in both negative affective state and control conditions. The implications of these findings for understanding the role of optimism and affective states, in determining the judgments about the likelihood of future events are discussed.     

Who is good at this game? Linking an activity to a social category undermines children's achievement

Children's achievement-related theories have a profound impact on their academic success. Children who adopt entity theories believe that their ability to perform a task is dictated by the amount of natural talent they possess for that task--a belief that has well-documented adverse consequences for their achievement (e.g., lowered persistence, impaired performance). It is thus important to understand what leads children to adopt entity theories. In the experiments reported here, we hypothesized that the mere act of linking success at an unfamiliar, challenging activity to a social group gives rise to entity beliefs that are so powerful as to interfere with children's ability to perform the activity. Two experiments showed that, as predicted, the performance of 4- to 7-year-olds (N = 192) was impaired by exposure to information that associated success in the task at hand with membership in a certain social group (e.g., "boys are good at this game"), regardless of whether the children themselves belonged to that group.     

Natural extinction: A criterion shift phenomenon

Previous detection performances obtained in a multi-varied contrast environment showed that observers tend to report significantly less the occurrence of the relatively lower contrast targets and significantly more the occurrence of the higher contrast ones than in conditions where each of these stimuli was tested in isolation (Gorea & Sagi, 2000). This criterion shift phenomenon is a form of contrast-dependent extinction in normal observers. To add more ground to the analogy between this type of “natural” extinction and the stroke-related one, we present a series of experiments where identical targets are displayed (1) at the same eccentricity but in opposite hemifields (along both the horizontal and vertical meridians), (2) at different eccentricities, and (3) where different spatial frequency targets of equal contrasts are displayed at the same eccentricity. Hemifield, eccentricity, and spatial frequency manipulations were intended to entail sensitivity differences for identical contrast stimuli. Some observers showed up to 3 and 1.5 d'-units differences between their left and right and between their upper and lower hemifields, respectively. Although observers may show significant response biases even for isolated stimuli as well as for equally visible ones presented together, it is always the case that they use higher response criteria (extinction) for the less visible targets and lower response criteria for the more visible ones (counter-extinction) when these stimuli are mixed in one experimental block. The observed criterion shifts translate into as much as three times more “Not seen” responses for the less visible targets and into about 1.3 times more “Seen” responses for the more visible ones. Taken together, the present data support the notion that at least some forms of extinction (and perhaps neglect) are contingent on relative sensory/perceptual impairments and that they reflect more or less drastic forms of criterion/decision shifts.
