Emotion deficits in schizophrenia: timing matters

The past two decades of research on emotional response in schizophrenia has demonstrated that people with schizophrenia do not have a marked deficit in reported emotional experience in the presence of emotionally evocative stimuli. However, the extent to which people with schizophrenia maintain their emotional state to guide future behavior remains a largely unexplored area of investigation. In the present study, we tested hypotheses about whether people with schizophrenia maintained their emotional state in the absence of emotionally evocative stimuli. In addition to reported emotional experience, we measured startle response magnitude both during the viewing and after the offset of emotional pictures to assess whether people with schizophrenia (n = 31) and without schizophrenia (n = 28) differ in their patterns of immediate response to emotional pictures and in their patterns of maintenance of these responses. Our findings indicated that people with and without schizophrenia did not differ in their self-report or startle response magnitude during presentation of emotional pictures. However, healthy controls maintained these responses after the stimuli were removed from view, but people with schizophrenia did not.     

Touching matters: Embodiments of intimacy

Touch is, I propose, a foundational, “intercorporeal” form of intimacy. Such intercorporeal intimacy precedes developmentally and undergirds permanently the “intersubjective” intimacy that is possible between adult subjects. For, it is in the affective intimacy of touching and being touched that we first realize (i.e., make real, actualize) both a coexistence or participation with other bodies, and an organization and differentiation of ourselves as embodied beings. Section 1 lays out phenomena of interpersonal (and interanimal) relations that require thinking touch as much more than either the exploration of a physical surface by an embodied subject or a conventional form of communication: I note the powerful existential effects of being or not being touched. In Section 2, I recall philosopher Maurice Merleau-Ponty’s account of embodiment, focusing on features that provide resources for understanding touch. I argue that touching must be understood as potentially transformative of the toucher, that “being touched” can equally be transformative, and that touching and being touched are inherently intertwined. This intertwining and transformative power is what makes touch an intercorporeal form of intimacy and accounts for its ability to inaugurate and enliven, at the affective level, our sense of self as differentiated from and in relation to others.     

Language and Operations in Children's Class Inclusion Reasoning: The Operational Semantic Theory of Reasoning

In this article we critique two prominent theories of reasoning—mental logic and mental models—and argue that reasoning does not consist of either applying logical rules or constructing mental models. Instead, we propose anoperational semantictheory of reasoning, according to which reasoning is based on children's operational understanding of key terms in a given problem. We then go on to consider an important recent developmental theory of reasoning, fuzzy-trace theory. In order to illustrate the view of reasoning proposed here we report a study of class inclusion. Dramatic differences in class inclusion performance were found as the result of linguistic context; performance was significantly higher when an explicit request for a subclass comparison preceded the class inclusion question as compared to a standard condition when the class inclusion question alone was asked. This was the case, however, only when the prior subclass comparison question referred to the same dimensions as the class inclusion question and not when irrelevant subclasses were referred to. Children's performance was also better when they sorted the materials into the supraordinate class as compared to the subclasses, but not when the experimenter sorted them for the child. These effects due to the operational and linguistic manipulations are discussed in terms of a generaloperational semantictheory of reasoning.     

Varieties of Reasoning: Assessing Adequacy

Helmut Reich's theory of relational and contextual reasoning is a courageous initiative for the resolution of cognitive conflicts between apparently incompatible or incommensurable views. Built upon Piagetian logico‐mathematical reasoning, cognitive complexity theory, and dialectical and analogical reasoning, it includes the development of a both/and logic inclusive of binary either/or logic. Reich provides philosophic, theoretical, and even initial empirical support for the development of this form of reasoning along with a heuristic for its application. A valuable step beyond the limits of binary, static, and formal reasoning, it takes relationship, context, and perspectival variations seriously in an explicitly reflective and iterative system. We can and do address conflicts not resolvable by conventional appeals to logic or evidence, including those at epistemic boundaries or produced by belief‐commitment differences. Although this form of reasoning has real promise, including stepping beyond complementarity in the religion‐science dialogue, it seems better directed to causally explanatory theories than to other forms of rendering meaning. Finally, its coextension requirement may render it problematic where functionally coherent explananda cannot be identified or are themselves produced or constituted by a belief system.     

Metaphor comprehension in Alzheimer's disease: novelty matters

The comprehension of non-literal language was investigated in 20 probable Alzheimer's disease (pAD) patients by comparing their performance to that of 20 matched control subjects. pAD patients were unimpaired in the comprehension of conventional metaphors and idioms. However, their performance was significantly lower in the case of non-conventional (novel) metaphor comprehension. This ability was not related to global cognitive deterioration or to deficits in the cognitive domains of attention, memory and language comprehension. On the other hand, the impairment in verbal reasoning appeared to be relevant for both novel and conventional metaphor comprehension. The relationship between novel metaphor comprehension and performance in the visual-spatial planning task of the Behavioral Assessment of the Dysexecutive Syndrome (BADS) suggests that executive impairment, possibly related to prefrontal dysfunction, may be responsible for the pAD patients' poor performance in novel metaphor comprehension. The present findings suggest a role of the prefrontal cortex in novel metaphor comprehension.     

Ethical decision-making in research: Identifying all competing interests

Ethical dilemmas are the result of conflicts between potential benefits or harms for two or more competing interests. Therefore, ethical decision-making implies a responsibility to identify those interests, harms, and benefits. For this purpose, researchers have responsibilities to the research, the subjects of research, other researchers, the institution, society, the environment, and self.     

Age of acquisition in sport: starting early matters

Although the age at which a skill is learned (age of acquisition [AoA]) is one of the most studied predictors of success in domains ranging from language to music, very little work has focused on this factor in sports. In order to uncover how the age at which a skill is learned relates to how athletes cognitively represent that skill, we asked a group of skilled golfers who learned to play golf before (early learners) or after (late learners) the age of 10 to take a series of putts on an indoor putting green. Golfers putted in isolation (single-task condition), while monitoring a stream of words presented over a loudspeaker (dual-task condition), or while being instructed to attend to specific aspects of their golf swing (skill-focused condition). Early and late learners putted equally well in the single-task and dual-task conditions. However, in the skill-focused condition, golfers who learned earlier performed worse than those who learned later. The results are consistent with the notion that AoA influences the manner in which sports, like other domains such as language and music, are represented in memory.     

The Development of Professional Counseling in Botswana

Among African countries, Botswana stands out for achieving lasting political and economic stability, which has enabled the government to develop a strong system of educational and social services for its people. Development of professional counseling in the country has occurred both through targeted efforts to provide a strong system of guidance services in schools and in response to the impact of the HIV/AIDS epidemic. This article reviews the development of professional counseling in Botswana and highlights trends likely to shape its future.     

Mirror reversal: Empirical tests of competing accounts

In a mirror, left and right are said to look reversed. Surprisingly, this very familiar phenomenon, mirror reversal, has still no agreed-upon account to date. This study compared a variety of accounts in the light of empirical data. In Experiment 1, 102 students judged whether the mirror image of a person or a character looked reversed or not in 15 settings and also judged the directional relation between its components. In Experiment 2, 52 students made the reversal judgements in 13 settings. It was found for the first time that a substantial proportion of people denied the left–right mirror reversal of a person, whereas virtually all of them did recognize that of a character. This discrepancy strongly suggested that these two kinds of mirror reversal are produced by different processes, respectively. A number of findings including this discrepancy clearly contradicted two accounts that are currently active: the one based on the priority of the up–down and front–back axes over the left–right axis, and the one based on the physical rotation of an object. All the findings were consistent with an account that considered mirror reversal a complex of three different phenomena produced by three different processes, respectively.

Evidence for Mental-model-based Reasoning: A Comparison of Reasoning with Time and Space Concepts

Johnson-Laird (1983) has argued that spatial reasoning is based on the construction and manipulation of mental models in memory. The present article addresses the question of whether reasoning about time relations is constrained by the same factors as reasoning about spatial relations. An experiment is reported that explored the similarities and the differences in the performance of subjects in comparable spatial and temporal reasoning tasks. The results indicated that, in both the temporal and the spatial content domains, the data were in agreement with the view that subjects solved problems by constructing models in memory rather than with a logical rule conceptualisation of reasoning. An analysis of the premise-reading times on the basis of premise-linking order provided support for an on-line process of mental models construction, and offered an explanation for the finding that spatial problems that did require an inference of transitivity were easier than problems that did not. No essential differences in processing and performance were observed across the two content domains, although in the time domain the correctness data were in agreement with both the mental models theory and the logical rules view. The results are discussed with respect to the mental models theory and the structural characteristics of the problems.     

Ethical issues in field research: balancing competing values.

An ethical issue becomes a dilemma when the psychologist is pulled in different directions by competing values. This paper will focus on the conflict between experimental and ethical values inherent in field research. The problem has special significance in community psychology, which gives priority to studying, in natural settings, those affected by social problems. An example is given of research that required observation of family interaction in the homes of convicted child abusers. The case demonstrates that the value of ecological validity often conflicts with the need to protect privacy and obtain uncoerced consent. Other ethical constraints, including the duty to report lawbreaking and to protect the public from harm, may threaten research validity.
