Testing visual short-term memory of pigeons (Columba livia) and a rhesus monkey (Macaca mulatta) with a location change detection task

Change detection is commonly used to assess capacity (number of objects) of human visual short-term memory (VSTM). Comparisons with the performance of non-human animals completing similar tasks have shown similarities and differences in object-based VSTM, which is only one aspect (“what”) of memory. Another important aspect of memory, which has received less attention, is spatial short-term memory for “where” an object is in space. In this article, we show for the first time that a monkey and pigeons can be accurately trained to identify location changes, much as humans do, in change detection tasks similar to those used to test object capacity of VSTM. The subject’s task was to identify (touch/peck) an item that changed location across a brief delay. Both the monkey and pigeons showed transfer to delays longer than the training delay, to greater and smaller distance changes than in training, and to novel colors. These results are the first to demonstrate location-change detection in any non-human species and encourage comparative investigations into the nature of spatial and visual short-term memory.     

The decline of cooperation,the rise of competition: developmental effects of long‐term social change in Mexico

Using Greenfield's theory of sociocultural change and human development as a point of departure, we carried out two experimental studies exploring the implications of decades of globalised social change in Mexico for children's development of cooperation and competition. In rural San Vicente, Baja California, the baseline was 1970 and the historical comparison took place 40 years later. In Veracruz, the baseline was 1985 and the historical comparison took place 20 years later. In Veracruz, children were tested in both rural and urban settings. We hypothesized that cooperative behavior would decrease in all three settings as a result of the sociocultural transformations of the past decades in Mexico. The Madsen Marble Pull Game was used to assess cooperative and competitive behavior. As predicted by Greenfield's theory of social change and human development, the Marble Pull procedure revealed a striking decrease over time in levels of cooperative behavior, with a corresponding rise in competitive behavior, in all three settings.     

Integrating Mental Health Services into a General Hospital in Puerto Rico

The prevalence of mental health problems in the general population should be carefully considered. The literature has reported a high co-morbidity of medical and mental illnesses; therefore, collaborative efforts incorporating psychological services into medical settings are imperative. In Puerto Rico, this is not a regular practice in general hospitals. Improving access to mental health services is a challenge and requires the creation of new venues within the healthcare system. This paper describes the theoretical framework, mission, and objectives of the Clinical Psychology Services Program (CPSP) implemented at Damas Hospital in Puerto Rico. From December 2002 to December 2010, a total of 13,580 visits were made to inpatients in diverse clinical units of the hospital; 61 % of all inpatients evaluated met the criteria for at least one mental health disorder based on the DSM-IV-TR. The CPSP’s outcomes highlight the acceptance and relevance of incorporating mental health services and clinical psychologists into general hospitals.     

Constructing Cultural Competence: Perspectives of Family Therapists Working with Latino Families

This article focuses on developing an understanding of how nine therapists working with Latino families construct the idea of cultural competence in the counseling room. In-depth interviews were conducted and analyzed yielding five themes in cultural competence from the therapists' perspectives: the use of language in therapy; the impact of social class, gender, and power on the therapeutic relationship; immigration and culture clash; definitions of family; and unique constructions of cultural competence. The therapists'narratives in this study are best understood through a postmodern paradigm suggesting that the field of psychotherapy needs to move beyond a “checklist” modernistic approach to developing cultural competency.     

Self‐Monitoring and Counseling Skills: Skills‐Based Versus Interpersonal Process Recall Training

The purpose of this study was to investigate the role of personality traits of counselors‐in‐training with regard to counseling performance. There were no differences in pretest or posttest scores on the Skilled Counseling Scale (SCS) of high and low self‐monitoring counselors‐in‐training. Skill attainment may have more effect on personality traits than traits have on skill attainment. Both Interpersonal Process Recall (IPR) and Skilled Counselor Training Model (SCTM) groups improved their scores on the SCS, but the SCTM group improved significantly more than the IPR group.     

Neural correlates of coherent and biological motion perception in autism

Recent evidence suggests those with autism may be generally impaired in visual motion perception. To examine this, we investigated both coherent and biological motion processing in adolescents with autism employing both psychophysical and fMRI methods. Those with autism performed as well as matched controls during coherent motion perception but had significantly higher thresholds for biological motion perception. The autism group showed reduced posterior Superior Temporal Sulcus (pSTS), parietal and frontal activity during a biological motion task while showing similar levels of activity in MT+/V5 during both coherent and biological motion trials. Activity in MT+/V5 was predictive of individual coherent motion thresholds in both groups. Activity in dorsolateral prefrontal cortex (DLPFC) and pSTS was predictive of biological motion thresholds in control participants but not in those with autism. Notably, however, activity in DLPFC was negatively related to autism symptom severity. These results suggest that impairments in higher-order social or attentional networks may underlie visual motion deficits observed in autism.     

Family Caregivers of Women with Physical Disabilities

Cross-sectional, correlational analyses of data from two separate studies were conducted to examine the correlates of adjustment among family caregivers of women with disabilities. Participants included 40 caregivers of women with spinal cord injuries in the first study and 53 caregivers of women with cerebral palsy, traumatic brain injury, and other neuromuscular disabilities in the second study. It was hypothesized that a negative problem-solving style would be associated with greater caregiver distress in both studies, and that caregiver adjustment would be associated with care recipient depression in the second study. As expected, results indicated that a higher negative orientation toward solving problems was associated with caregiver depression and lower well-being. However, in the second study, caregiver characteristics were not associated with care recipient depression. These data indicate that considerable variability exists in caregiver adjustment. Methodological limitations and the implications for research, service, and policy formation are! discussed.     

Parent‐implemented treatment for automatically maintained stereotypy

Automatically maintained stereotypy is common among children with autism spectrum disorder. The purpose of this study was to evaluate the effect of a multicomponent parent‐implemented intervention on the reduction of motor stereotypy for a child with autism. A 2‐year‐old child and her father participated in this study. The effect of a parent‐implemented intervention was evaluated using an alternating treatment design. The results indicated that the parent‐implemented treatment package including differential reinforcement, response blocking, and a competing stimulus decreased automatically maintained motor stereotypy.     

Use of three depression scales for evaluation of pretreatment severity and of improvement after treatment

We investigated the Castilian Spanish versions of three scales (the Hamilton Rating Scale for Depression, the Carroll Rating Scale for Depression, and the Montgomery-Asberg Depression Rating Scale) as to their suitability for classifying major depression patients in four levels of severity prior to treatment with tricyclic antidepressants, and also as to their suitability for classifying these patients in four improvement levels when administered posttreatment. Although the scales behaved quite similarly, each was most efficient at the task for which it had been designed, i.e., severity rating for the Hamilton and Carroll scales, improvement rating for the Montgomery-Asberg scale.     

Music perception and octave generalization in rhesus monkeys

Two rhesus monkeys were tested for octave generalization in 8 experiments by transposing 6- and 7-note musical passages by an octave and requiring same or different judgments. The monkeys showed no octave generalization to random-synthetic melodies, atonal melodies, or individual notes. They did show complete octave generalization to childhood songs (e.g., "Happy Birthday") and tonal melodies (from a tonality algorithm). Octave generalization was equally strong for 2-octave transpositions but not for 0.5- or 1.5-octave transpositions of childhood songs. These results combine to show that tonal melodies form musical gestalts for monkeys, as they do for humans, and retain their identity when transposed with whole octaves so that chroma (key) is preserved. This conclusion implicates similar transduction, storage, processing, and relational memory of musical passages in monkeys and humans and has implications for nature-nurture origins of music perception.
