Toward the development of a feature-space representation for a complex natural category domain

This article reports data sets aimed at the development of a detailed feature-space representation for a complex natural category domain, namely 30 common subtypes of the categories of igneous, metamorphic, and sedimentary rocks. We conducted web searches to develop a library of 12 tokens each of the 30 subtypes, for a total of 360 rock pictures. In one study, subjects provided ratings along a set of 18 hypothesized primary dimensions involving visual characteristics of the rocks. In other studies, subjects provided similarity judgments among pairs of the rock tokens. Analyses are reported to validate the regularity and information value of the dimension ratings. In addition, analyses are reported that derive psychological scaling solutions from the similarity-ratings data and that interrelate the derived dimensions of the scaling solutions with the directly rated dimensions of the rocks. The stimulus set and various forms of ratings data, as well as the psychological scaling solutions, are made available on an online website (https://osf.io/w64fv/) associated with the article. The study provides a fundamental data set that should be of value for a wide variety of research purposes, including: (1) probing the statistical and psychological structure of a complex natural category domain, (2) testing models of similarity judgment, and (3) developing a feature-space representation that can be used in combination with formal models of category learning to predict classification performance in this complex natural category domain.     

Organizational citizenship behavior and counterproductive work behavior: Do males and females differ?

While there has been considerable research on gender differences in core task performance, gender differences in organizational citizenship behavior (OCB) and counterproductive work behavior (CWB) have been largely ignored. Gender-consistent roles of females as being supportive would lead to the prediction that females engage in more OCB and less CWB than males. Using meta-analytic data gathered across 395 samples, we found several (weak) gender differences in CWB but none in OCB. We explain null and weak relationships from the perspective of social role theory, especially regarding males' roles being career-focused.     

Parents’ Beliefs about Children’s Emotions and Parents’ Emotion-Related Conversations with Their Children

The goals of the current study were to describe parents’ emotion socialization patterns and to assess relations between parents’ emotion-related beliefs and socialization behaviors during conversations with their children. Participants were 125 parents and their 9- and 10-year-old children from three ethnic groups in the southeastern United States. Parents reported beliefs about children’s emotions. Parents and children were videotaped playing a board game to evoke emotion-related conversations, which were then coded for parents’ labeling, teaching, and encouragement of emotion. Parents used less labeling and teaching for positive than negative emotions, and greater encouragement for positive than negative emotions. Parents with stronger beliefs about the value of positive emotions engaged in less labeling of positive emotions, less teaching of all emotions, and less encouragement of negative emotions. Parents with stronger beliefs about the value of negative emotions engaged in more encouragement of negative emotions. Parents with stronger beliefs that all emotions are dangerous engaged in less labeling of negative emotions. The results of this study have potential clinical implications in helping clients to understand the foundational structures of their behaviors and how both beliefs and behaviors are distinct, yet interrelated constructs.     

A unified account of categorical effects in phonetic perception

Categorical effects are found across speech sound categories, with the degree of these effects ranging from extremely strong categorical perception in consonants to nearly continuous perception in vowels. We show that both strong and weak categorical effects can be captured by a unified model. We treat speech perception as a statistical inference problem, assuming that listeners use their knowledge of categories as well as the acoustics of the signal to infer the intended productions of the speaker. Simulations show that the model provides close fits to empirical data, unifying past findings of categorical effects in consonants and vowels and capturing differences in the degree of categorical effects through a single parameter.     

Consistency of supervisor and peer ratings of assessment interviews conducted by psychology trainees

Observation of counsellor skills through a one-way mirror, video or audio recording followed by supervisors and peers feedback is common in counsellor training. The nature and extent of agreement between supervisor–peer dyads are unclear. Using a standard scale, supervisors and peers rated 32 interviews by psychology trainees observed through a one-way mirror. Results indicated that peers and supervisors used similar dimensions to cluster the various competencies. Peers rated counsellor performance more positively for general counselling skills, but not for specialised techniques. Analyses revealed good supervisor–peer agreement for some items and poor agreement on others, with some differences being unacceptably large. The study has important implications for how feedback involving supervisors and peers might be managed and for peer supervision models.     

Note Taking and Note Reviewing Enhance Jurors' Recall of Trial Information

Jurors forget critical trial information and this can influence their verdicts. This study assessed (1) whether or not note taking during a trial improves mock jurors' recall of trial information and (2) whether or not reviewing these notes prior to recalling the trial offers any additional enhancement. Mock jurors first watched a trial video. Three‐quarters were permitted to take notes whilst watching it. One‐third of these mock jurors then reviewed their notes, one‐third mentally reviewed the trial only, and one‐third completed a filler task to prevent any form of reviewing. The remainder took no notes during the trial and also completed a filler task afterwards. All then had their memory of the trial assessed via free recall. The principal findings were (1) note taking enhanced recall of the trial and (2) note reviewing offered an additional recall enhancement. The applied implications of these findings are discussed.Copyright © 2016 John Wiley & Sons, Ltd.     

Functional connectivity dynamics during film viewing reveal common networks for different emotional experiences

Recent theoretical and empirical work has highlighted the role of domain-general, large-scale brain networks in generating emotional experiences. These networks are hypothesized to process aspects of emotional experiences that are not unique to a specific emotional category (e.g., “sadness,” “happiness”), but rather that generalize across categories. In this article, we examined the dynamic interactions (i.e., changing cohesiveness) between specific domain-general networks across time while participants experienced various instances of sadness, fear, and anger. We used a novel method for probing the network connectivity dynamics between two salience networks and three amygdala-based networks. We hypothesized, and found, that the functional connectivity between these networks covaried with the intensity of different emotional experiences. Stronger connectivity between the dorsal salience network and the medial amygdala network was associated with more intense ratings of emotional experience across six different instances of the three emotion categories examined. Also, stronger connectivity between the dorsal salience network and the ventrolateral amygdala network was associated with more intense ratings of emotional experience across five out of the six different instances. Our findings demonstrate that a variety of emotional experiences are associated with dynamic interactions of domain-general neural systems.     

Meaning Naturalism, Meaning Irrealism, and the Work of Language

I defend the hypothesis that organisms that produce and recognize meaningful utterances tend to use simpler procedures, and should use the simplest procedures, to produce and recognize those utterances. This should be a basic principle of any naturalist theory of meaning, which must begin with the recognition that the production and understanding of meanings is work. One measure of such work is the minimal amount of space resources that must go into storing a procedure to produce or recognize a meaningful utterance. This cost has an objective measure, called Kolmogorov Complexity. I illustrate the use of this measure for a naturalist theory of meaning by showing how it offers a straight solution to one of the most influential arguments for meaning irrealism: the skeptical challenge posed by Kripke’s Wittgenstein.     

Phenomenal experience and the measure of information

This paper defends the hypothesis that phenomenal experiences may be very complex information states. This can explain some of our most perplexing anti-physicalist intuitions about phenomenal experience. The approach is to describe some basic facts about information in such a way as to make clear the essential oversight involved, by way illustrating how various intuitive arguments against physicalism (such as Frank Jackson’s Knowledge Argument, and Thomas Nagel’s Bat Argument) can be interpreted to show that phenomenal information is not different in kind from physical information, but rather is just more information than we typically attribute to our understanding of a physical theory. I clarify how this hypothesis is distinct from Nagel’s claim that the theory of consciousness may be inconceivable, and then in conclusion briefly describe how these results might suggest a positive and conservative physicalist account of phenomenal experience.
