Probabilistic Inferences Under Emotional Stress: How Arousal Affects Decision Processes

Many models of decision making neglect emotional states that could affect individuals' cognitive processes. The present work explores the effect of emotional stress on people's cognitive processes when making probabilistic inferences. Two contrasting hypotheses are tested against one another: the uncertainty‐reduction and attention‐narrowing hypotheses of how emotional stress affects decision making. In the experimental study, emotional stress was induced through the use of highly aversive pictures immediately before each decision. Emotional state was assessed by both subjective (state anxiety, arousal, and pleasantness ratings) and objective (skin conductance) measures. The results show that emotional stress impacts decision making; in particular, emotionally aroused participants seem to have focused on the most important information and selected simpler decision strategies relative to participants in a control condition. The results are in line with the attention‐narrowing hypothesis and suggest that emotional stress can impact decision making through limited predecisional information search and the selection of simpler decision strategies.

How do social fears in adolescence develop? Fear conditioning shapes attention orienting to social threat cues

Social fears emerging in adolescence can have negative effects on emotional well-being. Yet the mechanisms by which these risks occur are unknown. One possibility is that associative learning results in fears to previously neutral social stimuli. Such conditioned responses may alter subsequent processing of social stimuli. We used a novel conditioning task to examine how associative processes influence social fear and attention orienting in adolescents. Neutral photographs were paired with socially rewarding or aversive stimuli during conditioning; a dot-probe task then assessed biases in attention orienting. The social conditioning task modified subjective ratings of the neutral stimuli. Moreover, for the neutral stimulus that was paired with the aversive stimulus, the strength of conditioning showed a relationship with subsequent attentional vigilance. The findings elucidate mechanisms by which negative peer experiences during adolescence may affect emotional processing.

The influences of valence and arousal on judgments of learning and on recall

Much is known about how the emotional content of words affects memory for those words, but only recently have researchers begun to investigate whether emotional content influences metamemory—that is, learners’ assessments of what is or is not memorable. The present study replicated recent work demonstrating that judgments of learning (JOLs) do indeed reflect the superior memorability of words with emotional content. We further contrasted two hypotheses regarding this effect: a physiological account in which emotional words are judged to be more memorable because of their arousing properties, versus a cognitive account in which emotional words are judged to be more memorable because of their cognitive distinctiveness. Two results supported the latter account. First, both normed arousal (Exp. 1) and normed valence (Exp. 2) independently influenced JOLs, even though only an effect of arousal would be expected under a physiological account. Second, emotional content no longer influenced JOLs in a design (Exp. 3) that reduced the primary distinctiveness of emotional words by using a single list of words in which normed valence and arousal were varied continuously. These results suggest that the metamnemonic benefit of emotional words likely stems from cognitive factors.     

Arousal and the Relationship Between Positive and Negative Affect: An Analysis of the Data of Ito,Cacioppo, and Lang (1998)

Research on positive and negative emotional states has supported several models of how those states relate to each other. Many studies suggest that they are independent, the bivariate view, while others suggest that they are inversely correlated, the bipolar view. Other research has shown that stress is a major moderator of the relationship; the affects become coupled under conditions of high stress, a contextual model, but are relatively independent otherwise. To expand the range of tests of this dynamic model of affect, we reanalyzed a data set initially reported by Ito, Cacioppo, and Lang (1998) on affect-eliciting picture stimuli. In that study, arousal was assessed separately from positive and negative affect, allowing investigation of a source of interaffect relationships different from stress, per se. Arousal interacted with positive and negative affect, showing both bivariate and bipolar relationships, and effects similar to stress. Affective reactions to the stimuli became more inversely correlated when the affects were high and interacting with higher arousal. The data supported the dynamic model of affect and suggest the need for further analyses of the linkages between stress, arousal, and reduced levels of emotional complexity.     

What you learn is what you see: using eye movements to study infant cross-situational word learning

Recent studies show that both adults and young children possess powerful statistical learning capabilities to solve the word-to-world mapping problem. However, the underlying mechanisms that make statistical learning possible and powerful are not yet known. With the goal of providing new insights into this issue, the research reported in this paper used an eye tracker to record the moment-by-moment eye movement data of 14-month-old babies in statistical learning tasks. Various measures are applied to such fine-grained temporal data, such as looking duration and shift rate (the number of shifts in gaze from one visual object to the other) trial by trial, showing different eye movement patterns between strong and weak statistical learners. Moreover, an information-theoretic measure is developed and applied to gaze data to quantify the degree of learning uncertainty trial by trial. Next, a simple associative statistical learning model is applied to eye movement data and these simulation results are compared with empirical results from young children, showing strong correlations between these two. This suggests that an associative learning mechanism with selective attention can provide a cognitively plausible model of cross-situational statistical learning. The work represents the first steps in using eye movement data to infer underlying real-time processes in statistical word learning.

Pathways to Reading Competence: Emotional Self-regulation,Literacy Contexts,and Embodied Learning Processes

Abstract

Reading competence is one of the main gateways to learning and serves as the foundation for nearly all academic subjects, but reading is not a natural skill. For beginning and struggling readers, the process of learning to read is often fraught with frustration. Thus, abilities to manage affect or emotions and maintain attention or focus (i.e. emotional self-regulation processes) are critical for literacy development and reading competence. Building on bio-social-ecological systems and contextual-developmental frameworks, we present a model of reading competence to integrate multidisciplinary empirical research on the fit between children’s emotional self-regulation processes and their literacy contexts and how these person-in-context dynamics influence reading competence through reading motivation and engagement. We present empirical research in support of the pathways in this model of reading competence, and call for increased multidisciplinary research that takes into consideration children’s literacy contexts and their neurobiological and behavioral assets as well as vulnerabilities in order to better understand the dynamical cognitive-emotional-motivational processes that underlie the development of reading competence from early childhood through young adulthood, including the timing and mechanisms of change to target for reading interventions to have optimal impact.     

An associative model of rat serial pattern learning in three-element sequences

Hypotheses ranging from subsymbolic to symbolic have been proposed to account for rat sequential behaviour, and in the subsymbolic domain alone there are multiple proposed subsymbolic processes or factors thought to affect serial behaviour. A behavioural study and computer simulations were conducted to evaluate these hypotheses, and a new computational associative model based on pairwise associations and generalization was evaluated. Seven 3-element sequences were selected for study that systematically (1) varied sequence discriminability, (2) varied reward magnitude, and (3) manipulated the order of food quantities. Neither element discriminability nor response enhancement subsymbolic processes in isolation were able to account for the behavioural data; however, simulations from the computational model known as the sequential pairwise associative memory (SPAM) model with a log-linear mapping of stimulus dimension items to food quantities correlated well with the behavioural data. SPAM accounts for differential element anticipation in different sequences by appealing to pairwise association of sequence events and generalization between cues as the principal factors mediating pattern tracking in three-element sequences.     

What's social about social learning?

Research on social learning in animals has revealed a rich variety of cases where animals--from caddis fly larvae to chimpanzees--acquire biologically important information by observing the actions of others. A great deal is known about the adaptive functions of social learning, but very little about the cognitive mechanisms that make it possible. Even in the case of imitation, a type of social learning studied in both comparative psychology and cognitive science, there has been minimal contact between the two disciplines. Social learning has been isolated from cognitive science by two longstanding assumptions: that it depends on a set of special-purpose modules--cognitive adaptations for social living; and that these learning mechanisms are largely distinct from the processes mediating human social cognition. Recent research challenges these assumptions by showing that social learning covaries with asocial learning; occurs in solitary animals; and exhibits the same features in diverse species, including humans. Drawing on this evidence, I argue that social and asocial learning depend on the same basic learning mechanisms; these are adapted for the detection of predictive relationships in all natural domains; and they are associative mechanisms--processes that encode information for long-term storage by forging excitatory and inhibitory links between event representations. Thus, human and nonhuman social learning are continuous, and social learning is adaptively specialized--it becomes distinctively "social"--only when input mechanisms (perceptual, attentional, and motivational processes) are phylogenetically or ontogenetically tuned to other agents.     

Theoretical accounts of spatial learning: A neurobiological view (commentary on Pearce, 2009)

Theories of learning have historically taken, as their starting point, the assumption that learning processes have universal applicability. This position has been argued on grounds of parsimony, but has received two significant challenges: first, from the observation that some kinds of learning, such as spatial learning, seem to obey different rules from others, and second, that some kinds of learning take place in processing modules that are separate from each other. These challenges arose in the behavioural literature but have since received considerable support from neurobiological studies, particularly single neuron studies of spatial learning, confirming that there are indeed separable (albeit highly intercommunicating) processing modules in the brain, which may not always interact (within or between themselves) according to classic associative principles. On the basis of these neurobiological data, reviewed here, it is argued that rather than assuming universality of associative rules, it is more parsimonious to assume sets of locally operating rules, each specialized for a particular domain. By this view, although almost all learning is associative in one way or another, the behavioural-level characterization of the rules governing learning may vary depending on which neural modules are involved in a given behaviour. Neurobiological studies, in tandem with behavioural studies, can help reveal the nature of these modules and the local rules by which they interact.     

Lesions of the Rat Nucleus Basalis Magnocellularis Disrupt Appetitive-to-Aversive Transfer Learning

Rats with selective lesions of the nucleus basalis magnocellularis (NBM) and sham-lesion control animals were tested in an operant appetitive-to-aversive transfer task. We hypothesized that NBM lesions would not affect performance in the appetitive phase, but that performance would be impaired during subsequent transfer to the aversive phase of the task. Additional groups of NBM lesion and control rats were tested in the avoidance condition only, where we hypothesized that NBM lesions would not disrupt performance. These hypotheses were based on the argument that the NBM is not necessary for simple association learning that does not tax attention. Both the appetitive phase of the transfer task and the avoidance only task depend only on simple associative learning and are argued not to tax attention. Consequently, performance in these tasks was predicted to be spared following NBM lesions. Complex, attention-demanding associative learning, however, is argued to depend on the NBM. Performance in the aversive phase of the transfer task is both attentionally demanding and associatively more complex than in either the appetitive or aversive tasks alone; thus, avoidance performance in the NBM lesion group was predicted to be impaired following transfer from prior appetitive conditioning. Results supported our hypotheses, with the NBM lesion group acquiring the appetitive response normally, but showing impaired performance following transfer to the aversive conditioning phase of the transfer task. Impairments were not attributable to disrupted avoidance learning per se, as avoidance behavior was normal in the NBM lesion group tested in the avoidance condition only.

Culture,self, and collectivist communication: linking culture to individual behavior

This study develops and demonstrates a theoretical framework and corresponding methodology to link variables at the culture level to the individual level and, then, to specific outcome variables. The authors argue that in order to advance theory about culture's influence on communication, researchers must begin to examine how culture affects individual level (psychological) processes and, subsequently, how these processes affect communication. The image of self, referred to as self-construal, is an ideal candidate to perform the role of linking culture to behavior. The self is shaped by cultural forces and affects many, if not all, communication behaviors. The proposed strategy is applied in the test of a path-analytic model linking cultural collectivism with interdependent self-construals and, ultimately, high-context communication. The discussion includes implications for theory development and possible applications to further research.     

Processing the emotions in words: The complementary contributions of the left and right hemispheres

A dual-process model is suggested for the processing of words with emotional meaning in the cerebral hemispheres. While the right hemisphere and valence hypotheses have long been used to explain the results of research on emotional stimulus processing, including nonverbal and verbal stimuli, data on emotional word processing are mostly inconsistent with both hypotheses. Three complementary lines of research data from behavioral, electrophysiological, and neuroimaging studies seem to suggest that both hemispheres have access to the meanings of emotional words, although their time course of activation may be different. The left hemisphere activates these words automatically early in processing, whereas the right hemisphere gains access to emotional words slowly when attention is recruited by the meaning of these words in a controlled manner. This processing dichotomy probably corroborates the complementary roles the two hemispheres play in data processing.     

The past thirty years of emotion research: appraisal and beyond

ABSTRACT

For this Special Issue, I highlight the past and present importance of appraisal theory as well as the challenges to its status as a total theory of emotions from the other functions of emotions: associative learning, self-regulation and social communication. This theoretical view applies both to emotion research in general and the specific fields of my interest in the emotions of moral judgment and intergroup processes. Methodologically, developments in analyses of large and more naturally occurring data sets will give an opportunity to square psychology’s structural models of discrete emotions with the more complicated reality that exists. Both for the field and for individual researchers picking up the study of emotions, my advice is to pay special attention to measures, their assumptions and their context.     

Adult attachment and memory of emotional reactions to negative and positive events

Relations between adult attachment and memory for earlier emotional reactions to negative and positive events were examined. Hypotheses were that avoidance would be associated with underestimating earlier negative affect, whereas anxiety would be associated with overestimating earlier negative affect. Also, both avoidance and anxiety were expected to relate to underestimating earlier positive affect intensity. Participants (119 college students) completed daily report forms three times a day for 4 days on which they described and rated their immediate emotional reactions to events within each time period. Approximately 10 days later, they were asked to estimate their immediate emotional reaction to one negative event and one positive event. Events were coded as interpersonal or non-interpersonal. Contrary to hypotheses, for those lower on avoidance, anxiety related to lower levels of recalled negative affect (i.e., greater underestimation) for negative interpersonal events. As expected, with positive events, anxiety and avoidance related to lower levels of recalled positive emotions. Results suggest that memory processes could be one explanation of how working models operate and are sustained over time.     

The roles of associative and executive processes in creative cognition

How does the mind produce creative ideas? Past research has pointed to important roles of both executive and associative processes in creative cognition. But such work has largely focused on the influence of one ability or the other—executive or associative—so the extent to which both abilities may jointly affect creative thought remains unclear. Using multivariate structural equation modeling, we conducted two studies to determine the relative influences of executive and associative processes in domain-general creative cognition (i.e., divergent thinking). Participants completed a series of verbal fluency tasks, and their responses were analyzed by means of latent semantic analysis (LSA) and scored for semantic distance as a measure of associative ability. Participants also completed several measures of executive function—including broad retrieval ability (Gr) and fluid intelligence (Gf). Across both studies, we found substantial effects of both associative and executive abilities: As the average semantic distance between verbal fluency responses and cues increased, so did the creative quality of divergent-thinking responses (Study 1 and Study 2). Moreover, the creative quality of divergent-thinking responses was predicted by the executive variables—Gr (Study 1) and Gf (Study 2). Importantly, the effects of semantic distance and the executive function variables remained robust in the same structural equation model predicting divergent thinking, suggesting unique contributions of both constructs. The present research extends recent applications of LSA in creativity research and provides support for the notion that both associative and executive processes underlie the production of novel ideas.     

Generality of a Theory of Collective Induction: Face-to-Face and Computer-Mediated Interaction,Amount of Potential Information,and Group versus Member Choice of Evidence

In order to assess the generality of a theory of collective induction that has previously been supported for face-to-face interaction (Laughlin and Hollingshead, Organizational Behavior and Human Decision Processes, 1995), three experiments compared face-to-face and computer-mediated interaction for four-person groups for three successive rule induction problems. The predictions of the theory fit the obtained probabilities of group hypotheses for distributions of member hypotheses better than four other plausible models for both face-to-face and computer-mediated groups, over four levels of potential information, and for group versus member choice of evidence. There were comparable numbers of correct hypotheses for face-to-face and computer-mediated interaction, increasing correct hypotheses with increasing potential information, and comparable numbers of correct hypotheses for group versus member choice of evidence. The three experiments indicate the generality of the theory for both traditional face-to-face interaction and computer-mediated interaction, four levels of potential information, and group versus member choice of information. The comparisons of face-to-face and computer-mediated interaction extend the emphasis on social communication processes on decision and idea generation tasks of previous research to social combination processes in the acquisition and processing of new information in cooperative rule learning.     

Passion in group: thinking about loving,hating, and knowing

In his early work, Bion (1961) established the goal of learning about and getting beyond the basic assumptions to become a work group. Later, in his structural theory of affect, passion became a key concept. Passion describes the necessary and sufficient condition for a psychotherapy group to be a work group. Passion is an intersubjective process of bearing and utilizing one's most basic affects to reach self-conscious emotional awareness. Bion postulated three primary affects: loving, hating, and knowing (LHK). A clinical example illustrates how the therapist may represent, mentally organize, and mobilize the group's potential for passion by attending to the evolution of his or her own affects. Passion transcends transference-countertransference in that an optimal level of personal meaning from LHK is achieved and utilized in emotional participation.
