A satisfied clientele seeking more diverse services: Latinos and the courts

This article assesses Latino views of the court system, both of their beliefs about the courts and their experiences with the courts. Relying primarily on the Latino over-sample of the National Center for State Courts (2000) survey of public attitudes toward the courts, we evaluate three aspects of the Latino-judicial relationship. First, we measure whether there are differences between Latino and non-Latino views of the courts. Second, we assess whether there are differences within the Latino community, particularly differences based on nativity, in Latino attitudes toward the courts. Finally, we assess the implications of Latino views of the courts for US society in general. We are particularly concerned about whether having a greater share of Latinos in the population will create new pressures to reform the judiciary.     

Interactive learning in the paradise fish (Macropodus opercularis): an ethological interpretation of the second-order conditioning paradigm

This study was aimed at the examination of ‘mental construction’ in paradise fish by interactive learning, which is suggested as an alternative hypothesis for backward or second-order conditioning. Avoidance of goldfish was established in paradise fish by presenting a harmless goldfish (a novel stimulus) after an aversive event (mild electric shocks) in the dark compartment of a shuttle tank. It was found that this avoidance depended on context pre-exposure. Experiment 1 was designed to study the effect of mild shocks on shuttling activity in a familiar context. Experiment 2 aimed at establishing fear-conditioning to the goldfish in a higher-order conditioning paradigm. In the course of training, unpaired stimuli were presented in the dark compartment of the shuttle tank in such a manner that the presentation of mild shocks (20 mA) preceded the encounter with a harmless fish (goldfish). Experiment 3 demonstrated the role of context pre-exposure in interactive learning. Results indicate that (1) while 60 mA shocks resulted in avoidance of the dark compartment, the 20 mA mild shocks affected exploratory behaviour; (2) after pre-exposure to the training environment, paradise fish avoided the dark compartment containing goldfish provided that subjects had previously encountered mild, explorative shocks there; (3) this conditioned fear, a ‘mental construction’ of a potential danger, was proved to be transferable to another context and was consequently aimed specifically at the goldfish, a living being, rather than the training context; (4) the pre-exposure to the shuttle tank was an important part of this training procedure, that is, only subjects habituated to the shuttle tank avoided the goldfish. Results are discussed in the framework of the Interactive Learning Hypothesis, which has been developed as an ethological approach to a higher-order conditioning paradigm.

Links between mothers' and children's social competence and associations with maternal adjustment.

Extended previous research on family factors related to children's social competence by examining links between 3 domains of maternal social competence (social skills, social frames, network size) and 3 domains of children's social competence (social skills, peer-rated social preference, and network size) in a sample of 78 mothers and their kindergarten children (42 girls, 36 boys). The mediational role of maternal social competence in the association between mothers' depression and interpersonal sensitivity symptoms and children's social competence was also tested. Results supported associations between all 3 domains of mothers' and children's social competence, with maternal social skills the most frequent predictor of children's social competence. Gender differences suggested that maternal social competence was more strongly related to sons' peer acceptance and daughters' social skills. A mediational model received preliminary support for girls, with maternal psychological symptoms related to girls' social competence via maternal social skills. Implications include the need for continued study of maternal social competence as a family factor related to children's peer functioning and the development of family-based interventions for young children experiencing peer problems.     

United we stand, divided we fall: the education and training needs of clinical child psychologists

Reviews efforts to delineate training needs for psychologists who are providing clinical services to children, adolescents, and families. In particular, this article (a) describes efforts of clinical child and other psychologists who work with children, adolescents, and families to develop education and training guidelines; (b) discusses the overlap among various child and adolescent providers within psychology; and (c) highlights several key competencies that have been identified as important for all psychologists in practice roles with children and adolescents. In particular, we emphasize the need for greater collaboration and integration among various psychological specialties that focus on children, adolescents, and families and for greater system-wide discussion of training needs and priorities.     

Ecological relevance of stereopsis in one-handed ball-catching

The aim of this study was to compare one-handed catching performance between catchers with high (n = 10) and low (n = 10) binocular depth vision or stereopsis. In two sessions of 90 trials, tennis balls were projected at three different velocities towards the subject's shoulder region. Participants with good stereopsis were more successful, although the difference in number of correct catches fell short of significance. More specifically, catchers with low stereopsis made more temporal errors, but no differences in spatial errors. As the velocity of the ball increased, the initiation of the catch was delayed and catching performance decreased. The finding that stereopsis affected timing of the catch challenges the 'monocular tau hypothesis' in the control of interceptive timing, while the velocity effect shows that the act of catching a ball is not initiated at a constant time-to-contact.     

Enhanced Cognitive Behavior Therapy: A Single Treatment for All Eating Disorders

Eating disorders are serious mental illnesses affecting a significant proportion of women and a smaller number of men. Approximately half of those with an eating disorder (ED) will not meet the criteria for anorexia or bulimia nervosa, and will be diagnosed with an eating disorder not otherwise specified (EDNOS). Until recently, there were no recommended treatments for EDNOS. This article provides an overview of enhanced cognitive behavior therapy, a validated treatment for all forms of EDs.     

Comprehension and utilisation of pointing gestures and gazing in dog–human communication in relatively complex situations

The aim of the present investigation was to study the visual communication between humans and dogs in relatively complex situations. In the present research, we have modelled more lifelike situations in contrast to previous studies which often relied on using only two potential hiding locations and direct association between the communicative signal and the signalled object. In Study 1, we have provided the dogs with four potential hiding locations, two on each side of the experimenter to see whether dogs are able to choose the correct location based on the pointing gesture. In Study 2, dogs had to rely on a sequence of pointing gestures displayed by two different experimenters. We have investigated whether dogs are able to recognise an ‘indirect signal’, that is, a pointing toward a pointer. In Study 3, we have examined whether dogs can understand indirect information about a hidden object and direct the owner to the particular location. Study 1 has revealed that dogs are unlikely to rely on extrapolating precise linear vectors along the pointing arm when relying on human pointing gestures. Instead, they rely on a simple rule of following the side of the human gesturing. If there were more targets on the same side of the human, they showed a preference for the targets closer to the human. Study 2 has shown that dogs are able to rely on indirect pointing gestures but the individual performances suggest that this skill may be restricted to a certain level of complexity. In Study 3, we have found that dogs are able to localise the hidden object by utilising indirect human signals, and they are able to convey this information to their owner.     

Acquired equivalence of cues by presentation in a common context in rats

It is well established that humans and other animals may treat two perceptually different cues alike, if the cues have been individually paired with a common antecedent or a common consequence. Recently, Molet et al. (Psychon Bull Rev 18:618–623, 2011) reported evidence for a new form of acquired equivalence in human conditional discrimination, namely context-mediated equivalence. In the present research, using a flavor conditioning procedure, we asked whether rats would show similar context-mediated equivalence to demonstrate that this new form of acquired equivalence is a general phenomenon. Rats experienced two flavor cues A and B each presented either in the same context, X, or each in its own distinctive context, X or Y. Subsequently, the rats experienced B with sucrose in a third context, Z, and then the generalization of conditioning to A was assessed. When tested in Context Z, consumption of A was more marked when A and B had both been presented in the same context than when they had been presented in two different contexts. Thus, importantly, in the absence of the training context, cues that shared a common context at different times came to be treated as equivalent. This represents the first evidence of context-mediated equivalence in a nonhuman species.
