The S-R information stream: Where’s the filter?

Pavlovian conditioning procedures, in which events such as tastes, lights, and sounds become predictors of food, water, and shocks, have been used for studying the role of the information filter in the selection of conditioned responses. Different models posit the filter at different locations in the S-R stream, but most models suggest either a pre-encoding filter, in which much information is discarded at an early stage of processing, or a post-encoding filter, in which the information is stored but not subsequently expressed in behavior. A selective review of the literature on cue-competition effects reveals a plethora of phenomena that support a post-encoding, but not a pre-encoding filter in Pavlovian processes.     

The S-S construct of expectancy versus the S-R construct of fear: which motivates the acquisition of avoidance behavior?

The authors provided a differential test between stimulus-stimulus (S-S) and stimulus-response (S-R) theory predictions in regard to the roles that the constructs of expectancy and of fear play in maintaining classically conditioned fear responding within the context of a human conditioned-avoidance paradigm. After the participants had developed sustained avoidance responding, their shock electrodes and avoidance response apparatus were removed to enhance the cognitive expectancy that the conditioned stimulus (CS) would not be followed by the unconditioned stimulus (UCS). This manipulation of expectancy was successful in 96% of the participants. The study was conducted over a 2-day period and involved 1 experimental group and 3 control groups. During the test trials, the authors used autonomic and self-report indices of fear to assess the presence or absence of fear to the CS. The data disconfirmed the prediction of the S-S theory that fear to the CS would be extinguished. The authors discuss the implications of this finding for S-S theories and for approaches in cognitive behavior therapy.     

Swimming against the Stream?: Mindfulness as a Psychosocial Research Methodology

In this article, we extend psychosocial research methodology by integrating a breaching experiment, influenced by ethnomethodological sociology, with aspects of mindfulness practice, influenced by Buddhist traditions. We offer an empirical investigation of what happens when researcher-participants subtly “swim against the stream” of normative public social conduct in a capital city setting. Our qualitative analysis explores a single case from a corpus of 172 first-person retrospective accounts of standing still and doing nothing in a busy, public place. We investigate the qualitative aspects of how one researcher-participant arguably adopted a mindful, beginner’s mind orientation toward the flow of psychosocial consciousness. We empirically investigate this psychosocial orientation of mindfulness by integrating Wetherell’s concept of affective-discursive practice with James’ stream of consciousness. Mindfulness offers a specific, embodied reorientation toward psychosocial flows. We discuss the methodological implications and limitations of this reorientation for psychosocial research.     

The Role of the Corpus Callosum in Interhemispheric Transfer of Information: Excitation or Inhibition?

The corpus callosum is the major neural pathway that connects homologous cortical areas of the two cerebral hemispheres. The nature of how that interhemispheric connection is manifested is the topic of this review; specifically, does the corpus callosum serve to communicate an inhibitory or excitatory influence on the contralateral hemisphere? Several studies take the position that the corpus callosum provides the pathway through which a hemisphere or cortical area can inhibit the other hemisphere or homologous cortical area in order to facilitate optimal functional capacity. Other studies suggest that the corpus callosum integrates information across cerebral hemispheres and thus serves an excitatory function in interhemispheric communication. This review examines these two contrasting theories of interhemispheric communication. Studies of callosotomies, callosal agenesis, language disorders, theories of lateralization and hemispheric asymmetry, and comparative research are critically considered. The available research, no matter how limited, primarily supports the notion that the corpus callosum serves a predominantly excitatory function. There is evidence, however, to support both theories and the possibility remains that the corpus callosum can serve both an inhibitory and excitatory influence on the contralateral hemisphere.     

Where's the beef? Putting personality back into personality assessment

This article attempts to demonstrate the value of using a psychoanalytic theory of personality for psychological testing. This approach has more clinical utility than a solely research-based one. It recasts test data into conceptually related constructs that have internal consistency to each other and are directly relevant to psychotherapeutic treatment. Such theoretical recasting serves an organizing function, an integrative function, a clarification function, and a predictive function for the clinical inference process. Furthermore, a psychoanalytically oriented approach to testing allows for the expansion in sources of data that one considers in the testing situation. Five different sources of data emerge from the testing situation once one refocuses on theoretical constructs rather than test signs. These include test scores, test content, the patient-examiner interaction, patient behavior, and examiner countertransference.     

Where Is the Information for Affordances?

Two questions have priority for a perception psychologist: What is perceived, and what is the information for it? What we perceive are the affordances of the world. Because perception is prospective and goes on over time, the information for affordances is in events, both external and within the perceiver. Hence, we must study perception of events if we would understand how affordances are perceived.     

Information on the Internet: How selective should we be?

Vast amounts of information are available on the Internet, and programs such as Mosaic provide users with easy access to text and multimedia files. Once a user has set up a host system, consideration must be given to what information will be made available. In addition to legal restrictions, the interests of potential users (those accessing the host system) should be considered when determining the kinds of information to be made available. If those maintaining these host systems are somewhat selective when making information availability decisions, the potential information “glut” may be attenuated.     

What is the Philosophy of Information?

Computational and information-theoretic research in philosophy has become increasingly fertile and pervasive, giving rise to a wealth of interesting results. In consequence, a new and vitally important field has emerged, the philosophy of information (PI). This essay is the first attempt to analyse the nature of PI systematically. PI is defined as the philosophical field concerned with the critical investigation of the conceptual nature and basic principles of information, including its dynamics, utilisation, and sciences, and the elaboration and application of information-theoretic and computational methodologies to philosophical problems. I argue that PI is a mature discipline for three reasons: it represents an autonomous field of research; it provides an innovative approach to both traditional and new philosophical topics; and it can stand beside other branches of philosophy, offering a systematic treatment of the conceptual foundations of the world of information and the information society.     

Where's the ball? Two- and three-year-olds reason about unseen events

Children 2, 2 1/2, and 3 years of age engaged in a search task in which they opened 1 of 4 doors in an occluder to retrieve a ball that had been rolled behind the occluder. The correct door was determined by a partially visible wall placed behind the occluder that stopped the motion of the unseen ball. Only the oldest group of children was able to reliably choose the correct door. All children were able to retrieve a toy that had been hidden in the same apparatus if the toy was hidden from the front by opening a door. Analysis of the younger children's errors indicated that they did not search randomly but instead used a variety of strategies. The results are consistent with the Piagetian view that the ability to use representations to guide action develops slowly over the first years of life.     

Where's the Action? Understanding What Works and Why in Relationship Education

The field of couples relationship education has come to a critical junction. We have generally demonstrated that our interventions work (at least in the short run) but to what extent have we shown that the skills and processes we teach are in fact responsible for the success of the intervention? In this paper we review progress made in understanding mechanisms of change in relationship education, explore limitations of this body of research, explicate the barriers that interfere with progress in understanding mechanisms of change in intervention research, and present recommendations on how to proceed from here. Although our goal in this paper is to focus more on issues in the field rather than to present a comprehensive review of the literature, we provide overarching research summaries to illustrate some of our points. We conclude with offering recommendations for the next generation of research in the couples relationship education field.     

Where's poppa? The relative lack of attention to the role of fathers in child and adolescent psychopathology.

Compared with mothers, fathers are dramatically underrepresented in clinical child and adolescent research. The author reviewed empirical and theoretical clinical child and adolescent literature to ascertain the reasons for this underrepresentation. Four somewhat interrelated factors are discussed: practical issues in participant recruitment, differential base rates of paternal vs. maternal psychopathology, theory-driven research based on sexist theories, and research assumptions based on outdated societal norms. Suggestions for future research are discussed, including parallel investigations of paternal characteristics whenever maternal characteristics are investigated, assessment of both similarities and differences in the role of fathers and mothers in child and adolescent psychopathology, and investigation of parenting factors for both fathers and mothers (e.g., time spent in actual caretaking, career vs. family orientation) in relation to child and adolescent psychopathology.     

Where's the House Party? Hazardous Drinking Behaviors and Related Risk Factors

The authors examined differences in drinking behaviors and related risk factors across campus housing at a women's liberal arts college. Participants (N = 362) living in residence-style housing or house-style residences completed self-report questionnaires. Results showed that students in residence hall-style houses reported higher levels of hazardous alcohol use and perceived that their college, housemates or roommates, and close peers are more permissive of alcohol use than did students living in house-style residences. Findings highlight the role of the environmental structure of a college campus on students' perceptions of alcohol use and their drinking behaviors. The authors discuss implications for college housing and programming.     

The cause of stuttering: What''s the question?

There is a consensus among speech-language pathologists that the cause of stuttering is unknown. This lack of understanding is not due to the lack of research effort, but it may be due to asking an unanswerable question. We may already know the causes of many of those behaviors that make up the general concept, stuttering, if we would ask more specific questions.
