Expression of negative affect during face‐to‐face interaction: a double video study of young infants' sensitivity to social contingency

The purpose was to assess infants' sensitivity to social contingency, taking affective state into account, during face‐to‐face interaction with the mother in a double video set‐up. Infants' behaviour during three sequences of live face‐to‐face interaction were compared to two sequences where the interaction between the infant and the mother was set out of phase, by presenting either the infant or the mother with a replay of their partners' behaviour during earlier live interaction. We found a significant negative correlation between the infant's degree of negative affect and the average time of looking at the mother during the live sequences. A median split was calculated to separate the infants into a high‐negative‐affect group and a low‐negative‐affect group on the basis of their emotional responses during the experiment. The low‐negative‐affect infants looked significantly more at their mothers than other foci during the live but not the replay sequences, while the high‐negative‐affect infants did not show this difference. The results suggest that 2–4‐month old infants are able to distinguish between experimental distortion of contingent aspects in live and replay sequences, but that this effect of the replay condition may not be shown by moderate to highly distressed infants. Our findings underline the importance of taking infants' emotional state into account in experiments intended to assess their capacity for intersubjective communication.

The Second Essential Tension: on Tradition and Innovation in Interdisciplinary Research

In his analysis of “the essential tension between tradition and innovation” Thomas S. Kuhn focused on the apparent paradox that, on the one hand, normal research is a highly convergent activity based upon a settled consensus, but, on the other hand, the ultimate effect of this tradition-bound work has invariably been to change the tradition. Kuhn argued that, on the one hand, without the possibility of divergent thought, fundamental innovation would be precluded. On the other hand, without a strong emphasis on convergent thought, science would become a mess created by continuous theory changes and scientific progress would again be precluded. On Kuhn’s view, both convergent and divergent thought are therefore equally necessary for the progress of science. In this paper, I shall argue that a similar fundamental tension exists between the demands we see for novel insights of an interdisciplinary nature and the need for established intellectual doctrines founded in the classical disciplines. First, I shall revisit Kuhn’s analysis of the essential tension between tradition and innovation. Next, I shall argue that the tension inherent in interdisciplinary research between, on the one hand, intellectual independence and critical scrutiny and, on the other hand, epistemic dependence and trust is a complement to Kuhn’s essential tension within mono-disciplinary science between convergent and divergent thought.     

Clinical Geropsychology: Implications for Practice in Medical Settings

Older adults are a rapidly growing segment of the population, who have high rates of chronic illness and who utilize health care resources heavily. Psychologists must become better prepared to work with older patients in geriatric settings, including geriatric assessment units, memory disorders clinics, and nursing homes. In addition, all psychologists will increasingly encounter older patients in environments such as primary care clinics, rehabilitation settings, and disease management programs focusing on problems that are prevalent in older patients (e.g., cancer, diabetes). Suggestions are offered for adaptation of usual clinical practice to address the special needs of older patients and their families, and recommendations made for advancing and expanding the practice of clinical geropsychology.     

Beyond Single-Mindedness: A Figure-Ground Reversal for the Cognitive Sciences

A fundamental fact about human minds is that they are never truly alone: all minds are steeped in situated interaction. That social interaction matters is recognized by any experimentalist who seeks to exclude its influence by studying individuals in isolation. On this view, interaction complicates cognition. Here, we explore the more radical stance that interaction co-constitutes cognition: that we benefit from looking beyond single minds toward cognition as a process involving interacting minds. All around the cognitive sciences, there are approaches that put interaction center stage. Their diverse and pluralistic origins may obscure the fact that collectively, they harbor insights and methods that can respecify foundational assumptions and fuel novel interdisciplinary work. What might the cognitive sciences gain from stronger interactional foundations? This represents, we believe, one of the key questions for the future. Writing as a transdisciplinary collective assembled from across the classic cognitive science hexagon and beyond, we highlight the opportunity for a figure-ground reversal that puts interaction at the heart of cognition. The interactive stance is a way of seeing that deserves to be a key part of the conceptual toolkit of cognitive scientists.     

Self-ratings of positive and negative affect and retrieval of positive and negative affect memories

Abstract

Based on analysis of self-ratings of mood, positive affect (PA) and negative affect (NA) have been proposed as basic, orthogonal mood dimensions (Watson & Tellegen, 1985). The present study asked subjects (N = 61) to not only provide self-ratings of PA and NA terms but also to retrieve personal memories associated with those terms. Self-rated PA was associated with latency to retrieve PA- but not NA-related memories; self-rated NA was associated with latency to retrieve NA- but not PA-related memories. Self-ratings of PA and NA were not significantly correlated, nor were retrieval latencies for PA and NA memories. Individual item correlations also revealed a strong direct relationship between self-ratings and retrieval latency. The dissociations involving a non-self report measure strengthen the distinction between PA and NA, and the individual item correlations are interpreted as showing that self-ratings of affect are based upon the ease of retrieval of personal memories.     

Estimating latent correlations between repeated testings

A model for longitudinal latent structure analysis is proposed. We assume that test scores for a given mental or attitudinal test are observed for the same individuals at two different points in time. The purpose of the analysis is to fit a model that combines the values of the latent variable at the two time points in a two-dimensional latent density. The correlation coefficient between the two values of the latent variable can then be estimated. The theory and methods are illustrated by a Danish dataset concerning psychic vulnerability.     

The reflecting team: dialogue and meta-dialogue in clinical work

A "stuck" system, that is, a family with a problem, needs new ideas in order to broaden its perspectives and its contextual premises. In this approach, a team behind a one-way screen watches and listens to an interviewer's conversation with the family members. The interviewer, with the permission of the family, then asks the team members about their perceptions of what went on in the interview. The family and the interviewer watch and listen to the team discussion. The interviewer then asks the family to comment on what they have heard. This may happen once or several times during an interview. In this article, we will first describe the way we interview the family because the interview is the source from which the reflections flow. We will then describe and exemplify the reflecting team's manner of working and give some guidelines because the process of observation has a tendency to magnify every utterance. Two case examples will be used as illustrations.     

Sufficient statistics and latent trait models

For questionnaires with two answer categories, it has been proven in complete generality that if a minimal sufficient statistic exists for the individual parameter and if it is the same statistic for all values of the item parameters, then the raw score (or the number of correct answers) is the minimal sufficient statistic. It follows that the model must by of the Rasch type with logistic item characteristic curves and equal item-discriminating powers.This paper extends these results to multiple choice questionnaires. It is shown that the minimal sufficient statistic for the individual parameter is a function of the so-called score vector. It is also shown that the so-called equidistant scoring is the only scoring of a questionnaire that allows for a real valued sufficient statistic that is independent of the item parameters, if a certain ordering property for the sufficient statistic holds.     

Cooperativity, priming, and 3-D surface detection from optic flow

Three experiments were conducted to determine whether the mechanisms responsible for the detection of three-dimensional (3-D) surfaces from optic flow operate in a cooperative manner. The first experiment was conducted to determine whether a hysteresis effect occurs for 3-D surface detection from optic flow. The results of the first experiment demonstrated a hysteresis effect with lower thresholds occurring for decreasing texture density than for increasing texture density. The second experiment used a priming methodology to determine whether this form of cooperativity was based on preactivation of shear detectors or preactivation of 2-D motion detectors. The results suggest that only shear detectors were primed. The third experiment utilized a similar methodology to determine whether a surface representation would produce a priming effect. We found no evidence that the priming effect found in the second experiment was the result of preactivation of a generic representation of the test stimuli. The results of the experiments, considered together, suggest priming of the mechanisms responsible for recovering shear.
