Methylphenidate reduces abnormalities of stimulus classification in adolescents with attention deficit disorder.

Forty-eight adolescents with attention deficit disorder (ADD) received placebo and methylphenidate (M = 35.21 mg/day) for 3 consecutive weeks each. ADD patients who received placebo in the first phase of treatment were compared with unmedicated normal adolescents. ADD and normal adolescents did not differ in slope of reaction time as a function of memory load in a Sternberg (1969) memory task. These results may be interpreted as reflecting normal rates of memory search in ADD. However, in comparison with normal subjects, ADD subjects made disproportionately more errors to targets and lacked faster latencies of the P3b component of event-related potentials for targets than nontargets. These findings suggest abnormalities in stimulus classification. Methylphenidate did not affect ADD patients' rates of memory search, but it did reduce misclassifications of targets at high memory loads. The drug also evoked the normal pattern of slower P3b latencies for nontargets by shortening latencies for targets. Thus the stimulant reduced ADD adolescents' abnormalities in stimulus classification.     

When a Cultural Prohibition is Effective: A Field Investigation1

Three conditions have been hypothesized by Allport (1934) to be necessary for normative compliance to occur: (a) the required behavior must seem to serve a purpose; (b) the required behavior must be described in a rule or law; (c) a fairly large proportion of the population must perform the required behavior. Evidence supporting each of the three hypotheses is reviewed. The presence or strength of three variables related to each of the three conditions was varied factorially in an experimental field study of conformity to a prohibition against pedestrian traffic. The three hypotheses were strongly supported: Significantly more pedestrians corriplied the greater the strength of the factors related to the conditions. No interactions were found between variables. In addition, no differences between males and females and between a campus and a suburban sample were obtained. The results are discussed in terms of the normative elements of cultural conformity and a distinction is made between true conformity and cultural conformity.     

Extent-of-motion thresholds under subject-relative and object-relative conditions

The experiment was designed to discover the threshold extent of motion at medium speeds amounting to 41, 82, and 164 min./sec., and to compare the perception of motion arising from subject-relative displacement with the perception of motion arising from object-relative displacement. Extent thresholds were found while velocity was kept constant. Different groups of ten Ss were used for each displacement velocity, and for each S the extent threshold was twice obtained by the method of constant stimuli, once under subjectrelative and once under object-relative displacement conditions. Sensitivity to brief displacements of a continuously visible target was high; average thresholds ranged from 1.0 to 4.4 min. under the various conditions employed. The thresholds were higher for subject-relative conditions and the slower displacement velocities and lower for objectrelative conditions and faster displacements.     

Secular humanitarians and the postsecular: reflections on Habermas and the Typhoon Haiyan disaster response

The international humanitarian system aims to save lives and alleviate suffering following disasters worldwide. Secular and faith-based actors make up the system, but the system can operate to a secular standard that may, some have argued, marginalise religious experience and well-being post-disaster. This article assesses what can be learned from examining secular humanitarianism from a postsecular perspective. Debate on secularity in the humanitarian system is reviewed, before Jürgen Habermas’s conception of the postsecular is proposed as a theoretical lens. Habermasian postsecularism invites the secular to take part in a process of ‘complementary learning’ with the religious. Results from interviews and focus groups in the Philippines following Typhoon Haiyan are used. Results show the reflexivity of secular individuals within the humanitarian system, with cases demonstrating co-operation and consideration of other views at the interpersonal level. Yet, at a system-wide level, instances of marginalisation of religion were noted, such as responses to requests for chapel reconstruction and psycho-social assistance. While some organisations made a contextualised decision that either maintained their strict secularity or negotiated a compromise, in other cases, these decisions were based on preconceptions rather than deliberation. Overall, a level of reflexivity required in Habermasian postsecularism was found, but there were also further opportunities for complementary learning.     

Constructions of social selves living with HIV/AIDS: A Jungian phenomenological study

This study explored sense of social well-being influences on self-identity and the stigma and discrimination among people living with HIV/AIDS (PLWHA). Informants were 15 PLWHA from a rural background in a South African community (female = 87%, age range = 26 to 64 years; and males = 13%, age range = 55 to 64 years). They completed semi-structured interviews on their lived experiences relating to a sense of social inclusion and belongingness. We thematically analysed the data, and interpreted the findings applying Jungian archetypes of the Self, Shadow, and Persona. Findings suggest PLWHA’s sense of a dominant Shadow to be a barrier to self-acceptance whereas a Persona (mask) was guided by a need to be socially acceptable. A positive sense of social well-being among PLWHA is important to their health and well-being.     

The relationship between therapeutic engagement,cognitive errors,and coping action patterns: An exploratory study

Aim: This exploratory study examined the relationship between clients’ involvement in therapy and their cognitive errors (CE) and coping action patterns (CAP). Method: Therapy sessions from N = 26 clients were rated for CE and CP using the CE and CAP methods. Client involvement was measured with the Positive and Negative Affect Schedule, as well as the . Results: The CEs’ ‘magnification of the negative or minimisation of the positive’ and ‘labelling’ were associated with measures of affective therapeutic engagement. The coping styles ‘negotiation’, ‘opposition’, ‘submission’, ‘isolation’, ‘support seeking’, ‘information seeking’, ‘delegation’, and ‘escape’ were found to be associated with affective and behavioural dimensions of therapeutic involvement. Conclusions: These findings provide preliminary supporting evidence that CE and CP are related to the extent to which clients engage in the work of therapy. Implications for researchers and therapists are discussed.     

Inertia tensor and weight-percept models of length perception by static holding

S. J. Lederman, S. R. Ganeshan, and R. E. Ellis (1996) reported an experiment demonstrating that for occluded rods of equal mass and length but different diameters length perception by static holding was larger for rods of smaller diameter. They concluded that participants inferred length from illusory weight percepts. However, rods of equal mass and length that differ in diameter also differ in the eigenvalues of their respective inertia tensors. In the present experiments, the authors manipulated the diameters (Experiment 1) and the inertial eigenvalues (Experiments 4 and 5) of statically held objects. As has been shown with wielded objects, perceived length was a function of the eigenvalues. Additional experiments failed to confirm the expectation from the weight-percept model that perceived length maps to the estimated weight (Experiments 2 and 3). Physical quantities, not psychological quantities, seem to explain length perception by static holding.
