Pragmatic expectations and linguistic evidence: Listeners anticipate but do not integrate common ground

When listeners search for the referent of a speaker’s expression, they experience interference from privileged knowledge, knowledge outside of their ‘common ground’ with the speaker. Evidence is presented that this interference reflects limitations in lexical processing. In three experiments, listeners’ eye movements were monitored as they searched for the target of a speaker’s referring expression in a display that also contained a phonological competitor (e.g., bucket/buckle). Listeners anticipated that the speaker would refer to something in common ground, but they did not experience less interference from a competitor in privileged ground than from a matched competitor in common ground. In contrast, interference from the competitor was eliminated when it was ruled out by a semantic constraint. These findings support a view of comprehension as relying on multiple systems with distinct access to information and present a challenge for constraint-based views of common ground.     

Maternal borderline personality disorder symptoms and adolescent psychosocial functioning

Borderline personality disorder (BPD) is characterized by severe disruption of interpersonal relationships, yet very little research has examined the relationship between maternal BPD and offspring psychosocial functioning. The present study examined 815 mothers and their 15-year-old children from a community-based sample to determine (1) if there is an association between mothers' BPD symptoms and the interpersonal functioning, attachment cognitions, and depressive symptoms of their offspring, and (2) if the association of maternal BPD and youth outcomes is independent of maternal and youth depression. Measures of youth psychosocial functioning included self, mother, interviewer rated, and teacher reports. Results indicated that there was a significant association between maternal BPD symptoms and youth outcomes, and that this association remained even after controlling for maternal lifetime history of major depression, maternal history of dysthymic disorder, and youth depressive symptoms. This study provides some of the first empirical evidence for a link between mother's BPD symptoms and youth psychosocial outcomes.     

Trends in Women's Participation at the Meetings of the Association for Behavior Analysis: 1975-2005

We examined women's participation, relative to men's, at the annual meetings of the Association for Behavior Analysis (ABA) between 1975 and 2005. Among our findings are upward trends in female presenters across formats (e.g., posters), types of authorship (e.g., first authors), and specialty areas (e.g., autism). Where women have attained parity, however, they are still often underrepresented, given their percentage of membership. Women also participate less than men as sole and invited authors and discussants and in the domains of basic research and conceptual analysis, but participate more than men in the applied domain. Data from the Journal of the Experimental Analysis of Behavior and the Journal of Applied Behavior Analysis show parallel but delayed trends toward parity in basic and applied research, whereas data from The Behavior Analyst show only modest gains in the conceptual domain. We discuss the gender disparities in ABA's more prestigious categories of participation (e.g., invited addresses) and across its content domains, as well as in science in general, and the role of social and cultural factors in producing the disparities and how behavior analysts might aid in correcting them.     

Social risk factors in Spanish youth and their impact on self-concept construction

This paper presents evidence from a psychosocial framework about the relationship among youth, work, and identity construction. The aims of this research were twofold. The first one was to analyze the working conditions of Spanish youth and their impact on individuals' biographies. The second one was to examine the effect of labor-related variables on construction/change of identity elements in Spanish youth. For this purpose, two research techniques were used: the Delphi method (103 experts sample from several entities and organizations closely related to our topic) and deep interviews (15 interviews with youths classified according to their relationship with the work market).     

Implicit theories of relationships: moderators of the link between conflict and commitment

In two studies, implicit theories of relationships were examined as moderators of the association between experienced conflict and commitment. Study 1 involved 128 individuals in heterosexual romantic relationships and employed an event-contingent diary procedure in which disagreements were recorded throughout a 10-day period. Study 2 was conducted in the laboratory and involved 75 heterosexual couples who discussed problems in their relationship, with commitment measured before and after discussion. Multilevel random coefficient models revealed that conflict was generally associated with lower commitment but less so with growth belief. Also, growth belief was most beneficial under negative relationship conditions, such as when one possessed a less favorable view of the partner to begin with and when the issue remained unresolved after discussion.     

Whether, when, and why Skinner published on biological participation in behavior

This paper brings some data to bear on the criticisms, claims, and arguments that Skinner (a) denied or dismissed biological participation in behavior, (b) addressed it only late in his career or more often later than earlier, or (c) addressed it only because of the overwhelming evidence for it or the criticisms that he had overlooked it. For this, we coded Skinner's every primary-source publication for three content categories (i.e., genetics, physiology, and evolution) and for the extent to which he addressed them (i.e., in publication titles, substantively, or in passing). Our findings are that Skinner addressed biological participation in over a third of his publications throughout his career, albeit more often later than earlier. The latter, however, is accounted for by an increase in his base rate of publication and in general conditions and specific events in his career, psychology, and science. The discussion addresses our research methods; the reasons for and refutations of the criticisms, claims, and arguments; and their sources.     

After-School Youth Development Programs: A Developmental-Ecological Model of Current Research

Although there has been a rapid increase in funding and attention to after-school programs, there is little understanding of how after-school programs impact children's developmental trajectories. The heterogeneity of American children makes it very unlikely that all children need after-school programming or that there is but one brand of after-school programming suitable for all youth. We discuss the numerous developmental and contextual factors that may influence which children benefit most from after-school programs as well as the nature of the after-school programs most beneficial to children's needs. The value of utilizing an ecological and developmental perspective to after-school program evaluation are presented, including the need for improved research designs and more detailed analyses of program type and services as well as a more complete determination of which children benefit the most from after-school participation.     

The time of our lives: life span development of timing and event tracking

Life span developmental profiles were constructed for 305 participants (ages 4-95) for a battery of paced and unpaced perceptual-motor timing tasks that included synchronize-continue tapping at a wide range of target event rates. Two life span hypotheses, derived from an entrainment theory of timing and event tracking, were tested. A preferred period hypothesis predicted a monotonic slowing of a preferred rate (tempo) of event tracking across the life span. An entrainment region hypothesis predicted a quadratic profile in the range of event rates that produced effective timing across the life span; specifically, age-specific entrainment regions should be narrower in childhood and late adulthood than in midlife. Findings across tasks provide converging support for both hypotheses. Implications of these findings are discussed for understanding critical periods in development and age-related slowing of event timing.     

Implicit transfer of motor strategies in mental rotation

Recent research indicates that motor areas are activated in some types of mental rotation. Many of these studies have required participants to perform egocentric transformations of body parts or whole bodies; however, motor activation also has been found with nonbody objects when participants explicitly relate the objects to their hands. The current study used positron emission tomography (PET) to examine whether such egocentric motor strategies can be transferred implicitly from one type of mental rotation to another. Two groups of participants were tested. In the Hand-Object group, participants performed imaginal rotations of pictures of hands; following this, they then made similar judgments of pictures of Shepard-Metzler objects. The Object-Object group performed the rotation task for two sets of Shepard-Metzler objects only. When the second condition in each group (which always required rotating Shepard-Metzler objects) was compared, motor areas (Area 6 and M1) were found to be activated only in the Hand-Object group. These findings suggest that motor strategies can be covertly transferred to imaginal transformations of nonbody objects.
