Early Language Impairment and Young Adult Delinquent and Aggressive Behavior

Clinic and forensic studies have reported high rates of language impairments in conduct disordered and incarcerated youth. In community samples followed to early adolescence, speech and language impairments have been linked to attention deficits and internalizing problems, rather than conduct problems, delinquency, or aggression. This study examines the young adult antisocial outcomes of speech or language impaired children. Language impaired boys had higher levels of parent-rated delinquency symptoms by age 19 than boys without language impairment, controlled for verbal IQ and for demographic and family variables. Language impaired boys did not differ from controls in self-reported delinquency or aggression symptoms on a standardized checklist; however, language impaired boys reported higher rates of arrests and convictions than controls. Language impairment was not related to aggression or delinquency in girls. We examine alternate models of the interrelationships between language, academics, and behavior, at ages 5, 12, and 19.     

Specialization and semantic organization: Evidence for multiple semantics linked to sensory modalities

The present article reviews the case for multiple systems in semantic memory and empirically evaluates a multiple semantics proposal based on sensory modalities. In the experiments, a conceptual switching cost paradigm was used (Pecher, Zeelenberg, & Barsalou, 2003), in which participants verified properties for concepts and verification time was compared for target trials (e.g., a dog can bark) that were preceded by context trials of either the same or a different modality (e.g., a bee can buzz or a horse can have spots). Experiment 1 involved a modality switch while controlling for the concept's category and demonstrated that when modalities were switched, a processing cost was incurred that could not be attributed to the latter dimension. Experiment 2 further supported this conclusion by showing that, in a reverse situation, the cost incurred when category was switched was at least smaller. The results are discussed by considering possible alternative amodal explanations and other data that have shown the influence of sensory information in conceptual processing.     

Self-conscious emotions and self-regulation in the promotion of condom use

Two prospective studies examined the self-regulatory role of anticipated negative self-conscious emotions (ANSCE) in the theory of planned behavior. In Study 1, 147 undergraduates reported condom attitudes, perceived norms, self-efficacy, ANSCE (shame and guilt) should they not use condoms, and intentions to use condoms during the coming 6 weeks. At a 6-week follow-up, ANSCE predicted condom use intentions and behavior and partially mediated the effect of attitudes and norms on both. Study 2 experimentally tested the social nature of self-consciousness in ANSCE; 61 female undergraduates read a scenario priming the private-self or social-self or were assigned to a no-scenario control. They reported condom attitudes, perceived control, ANSCE, condom use intentions, and a 6-week follow-up. ANSCE again predicted condom use intentions. A test of moderated mediation indicated that ANSCE influenced condom intentions more in the social-self condition than in the control condition. Implications of these findings are discussed.     

Visual experience is not necessary for efficient survey spatial cognition: evidence from blindness

This study investigated whether the lack of visual experience affects the ability to create spatial inferential representations of the survey type. We compared the performance of persons with congenital blindness and that of blindfolded sighted persons on four survey representation-based tasks (Experiment 1). Results showed that persons with blindness performed better than blindfolded sighted controls. We repeated the same tests introducing a third group of persons with late blindness (Experiment 2). This last group performed better than blindfolded sighted participants, whereas differences between participants with late and congenital blindness were nonsignificant. The present findings are compatible with results of other studies, which found that when visual perception is lacking, skill in gathering environmental spatial information provided by nonvisual modalities may contribute to a proper spatial encoding. It is concluded that, although it cannot be asserted that total lack of visual experience incurs no cost, our findings are further evidence that visual experience is not a necessary condition for the development of spatial inferential complex representations.     

Proactive interference effects on sentence production

Proactive interference refers to recall difficulties caused by prior similar memory-related processing. Information-processing approaches to sentence production predict that retrievability affects sentence form: Speakers may word sentences so that material that is difficult to retrieve is spoken later. In this experiment, speakers produced sentence structures that could include an optionalthat, thereby delaying the mention of a subsequent noun phrase. This subsequent noun phrase was either (1) conceptually similar to three previous noun phrases in the same sentence, leading to greater proactive interference, or (2) conceptually dissimilar, leading to less proactive interference. Speakers produced morethats (and were more disfluencies) before conceptually similar noun phrases, suggesting that retrieval difficulties during sentence production affect the syntactic structures of sentences that speakers produce.     

The performance of left-handed participants on a preferential reaching test

Previous research in our laboratory has examined the distribution of preferred hand (PH) reaches in working space with right-handed participants. In one study, we examined the effects of tool position and task demands on the frequency of PH reaches with right-handers (Mamolo, Roy, Bryden, & Rohr, 2004). We found that PH reaches were at a maximum within ipsilateral space, and predominated within contralateral space. This was mediated by the task demands, as shown by an increased frequency of PH reaches for the more skill demanding tasks. In the current study, we tested left-handed participants on the same procedure. Five different tools were placed in an array in front of the participant, who was required to reach for, and perform one of three tasks with the tool: Lift the tool; lift and Pantomime its use; or lift and Use the tool on its corresponding object. The results showed that PH reaches were at a maximum within ipsilateral space for all three tasks. Significantly fewer PH reaches were made for tools in contralateral space. In particular, almost no PH reaches were made for the Lift task at the most extreme contralateral position. This indicates the willingness of left-handers to use their non-preferred (i.e., right) hand. One possible explanation supported by these results is that left-handers have adapted to an environment designed for right-handers.     

Coping attitudes, sources, and practices among Black and Latino college students

We investigated 130 Black and Latino college students regarding their concerns, attitudes toward professional counseling, sources of support, and coping activities. We found that the Black and Latino cultural emphasis on interdependence influenced attitudes toward using professional resources such as a counselor. We also found a significant two-way interaction between gender and race for attitudes toward professional counseling: Black males had less favorable attitudes in comparison to Black females, while Latino males had more favorable attitudes than did Latino females. Both Black and Latino college students had favorable attitudes toward informal support networks. Differences between Black and Latino college students were found for reported concerns and coping sources. Implications for counseling theory, practice, and research are discussed.     

Self-reported reflective functioning and father–child interactions in a sample of fathers who have used intimate partner violence

Reflective functioning (RF) has been found to be associated with mother–child interactions, but less is known about the association of fathers’ self and child-focused RF and father–child relationships.  Fathers who have histories of intimate partner violence (IPV) are known to have poor RF, which may impact their father–child interactions.  The current study was designed to examine how types of RF are associated with father–child relationships.  Pretreatment assessments and recorded, coded father–child play interactions were used to examine associations among fathers’ history of adverse childhood experiences (ACES), RF and coded father-child play interactions in a sample of 47 fathers with a history of IPV use in the last 6 months with their coparent.  Fathers’ ACES and their child's mental states (CM) were associated with father-child dyadic play interactions.  Fathers with greater ACES and higher scores on CM had the most dyadic tension and constriction during play interactions.  Those with high ACES but low CM had scores similar to those with low ACES and low CM.  These results indicate that fathers who have used IPV and have a history of significant adversity may benefit from interventions to increase their child-focused RF and further improve their interactions with their children.     

Keeping Your Distance: Group Membership,Personal Space,and Requests for Small Favors1

The effects of group membership and interpersonal distance on interpersonal anxiety and compliance with a small request were explored. In a field experiment, people seated alone in the public eating area or a shopping mall were approached by one of two female confederates: an in-group member or an out-group member. Three different interpersonal distances were assumed by the confederates: near, medium, and far. The “medium” distance was the normative distance for interactions between strangers in the experimental situation. Although the out-group confederate aroused greater anxiety and obtained less compliance than the in-group confederate overall, these differences completely disappeared in the far-distance condition. It is suggested that one reason why out-group members are less likely to elicit compliance with a small request is that they arouse interpersonal anxiety on the part of potential helpers. The results of the present experiment indicate that this anxiety can be reduced (and compliance thereby increased) if the out-group member assumes a somewhat greater distance than is normally deemed appropriate for interactions between strangers.     

Semantic and formational clustering in deaf and hearing subjects’ free recall of signs

To investigate whether formational properties of sign language are used spontaneously to organize long-term memory, 16 deaf college students were given a free recall task with items that could be categorized either by shared semantic category or by shared sign language hand shape. Both presentation and response modes (signed or written) were varied between subjects. Analyses revealed no effects of mode on trials to criterion or number of items recalled at 1 week. The clustering that occurred was exclusively semantic, with significantly higher clustering scores during acquisition trials in subjects required to sign their responses. In Experiment 2, formational clustering was encouraged by including formational similarity as the only experimenter-defined basis of categorization, by increasing formational similarity within categories, and by testing only subjects with high signing skills. Input and output modes were again varied between subjects. Subjects were deaf college students with deaf parents (n = 10) or hearing parents (n = 16), and hearing adults with deaf parents (n = 8). Again, spontaneous clustering by formational similarity was extremely low. In only one case— deaf subjects with hearing parents given signed input—did formational clustering increase significantly across the eight acquisition trials. After the categorical nature of the list was explained to subjects at a 1-week retention session, all groups clustered output by formational categories. Apparently, fluent signers do have knowledge of the formational structure of signs, but do not spontaneously use this knowledge as a basis of mnemonic organization in long-term memory.
