Opposite effects of anxiety and depressive symptoms on executive function: The case of selecting among competing options

People constantly face the need to choose one option from among many, such as when selecting words to express a thought. Selecting between many options can be difficult for anyone, and can feel overwhelming for individuals with elevated anxiety. The current study demonstrates that anxiety is associated with impaired selection across three different verbal tasks, and tests the specificity of this finding to anxiety. Anxiety and depression frequently co-occur; thus, it might be assumed that they would demonstrate similar associations with selection, although they also have distinct profiles of symptoms, neuroanatomy and neurochemistry. Here, we report for the first time that anxiety and depressive symptoms counter-intuitively have opposite effects on selection among competing options. Specifically, whereas anxiety symptoms are associated with impairments in verbal selection, depressive symptoms are associated with better selection performance. Implications for understanding the mechanisms of anxiety, depression and selection are discussed.     

Facilitated communication: Better education through applied ideology

Facilitated communication (FC), or the provision of graduated assistance by staff in the selection of keys on a communication device by people with developmental disabilities, has become a widely used training technique. Although widespread anecdotal accounts of substantial training benefits and unanticipated communicative competence have been reported, controlled experimental and single subject studies have disclosed little evidence of unexpected competencies. We review research on FC, identify cognitive factors that may stimulate acceptance of this as a training method, and suggest procedures to be employed in individual validation situations when critical communications occur.     

Family conflict shapes how adolescents take risks when their family is affected

Numerous studies have established that the social context greatly affects adolescent risk taking. However, it remains unexplored whether adolescents' decision‐making behaviors change when they take risks that affect other individuals such as a parent. In the current study, we sought to investigate how the social context influences risky decisions when adolescents' behavior affects their family using a formalized risk‐taking model. Sixty‐three early adolescents (M_age = 13.3 years; 51% female) played a risk‐taking task twice, once during which they could make risky choices that only affected themselves and another during which their risky choices only affected their parent. Results showed that adolescents reporting high family conflict made more risky decisions when taking risks for their parent compared to themselves, whereas adolescents reporting low family conflict made fewer risky decisions when taking risks for their parent compared to themselves. These findings are the first to show that adolescents change their decision‐making behaviors when their risks affect their family and have important implications for current theories of adolescent risk taking.     

Autonomic functioning in reactive versus proactive aggression: The influential role of inconsistent parenting

Research has consistently supported autonomic nervous system (ANS) functioning as a predictor of aggressive behavior in youth. Several studies have further examined how the functioning of the sympathetic (SNS) and parasympathetic (PNS) branches of the ANS interact with environmental factors to predict behavioral outcomes. One factor that has yet to be studied in this context however, is parenting practices. Given that many interventions for externalizing behavior target parenting practices, such as increasing consistent discipline, it may be particularly important to assess whether parenting practices interact with SNS and PNS functioning in the child to influence risk for aggressive behavior. Therefore, the current study addressed this question by examining inconsistent discipline as a moderator of the relationship between baseline SNS versus PNS activity and reactive versus proactive aggression. Data were collected from a sample of fourth graders identified as at‐risk for aggression (N = 188). Results indicated that baseline SNS activity was positively related to proactive aggression under high levels of inconsistent discipline, but negatively related to proactive aggression under very low levels of inconsistent discipline. Baseline PNS activity was negatively associated with reactive aggression under low levels of inconsistent discipline. No main effects were found for SNS or PNS functioning and either form of aggression, emphasizing the importance of taking a biosocial approach to examining the predictors of aggressive behavior in at‐risk youth. Results from this study help to better understand the circumstances under which children are most likely to exhibit reactive versus proactive aggression, better informing targeted prevention and treatment.

     

The Bursts and Lulls of Multimodal Interaction: Temporal Distributions of Behavior Reveal Differences Between Verbal and Non‐Verbal Communication

Recent studies of naturalistic face‐to‐face communication have demonstrated coordination patterns such as the temporal matching of verbal and non‐verbal behavior, which provides evidence for the proposal that verbal and non‐verbal communicative control derives from one system. In this study, we argue that the observed relationship between verbal and non‐verbal behaviors depends on the level of analysis. In a reanalysis of a corpus of naturalistic multimodal communication (Louwerse, Dale, Bard, & Jeuniaux, 2012 ), we focus on measuring the temporal patterns of specific communicative behaviors in terms of their burstiness. We examined burstiness estimates across different roles of the speaker and different communicative modalities. We observed more burstiness for verbal versus non‐verbal channels, and for more versus less informative language subchannels. Using this new method for analyzing temporal patterns in communicative behaviors, we show that there is a complex relationship between verbal and non‐verbal channels. We propose a “temporal heterogeneity” hypothesis to explain how the language system adapts to the demands of dialog.     

Premarital affect as a predictor of postnuptial marital satisfaction

Although well established with newlywed couples, studies examining the association between affective communication during conflict and later relationship satisfaction yield inconsistent results with premarital samples. The current study reexamined this association with a different method of coding affect observed during discussions of separate male‐ and female‐selected problem topics and contemporary methods for modeling dyadic data. The sample included 32 engaged couples assessed across the transition to marriage. Premarital affect correlated with concurrent and postnuptial relationship satisfaction. Men's and women's premarital affect also predicted changes in women's relationship satisfaction across the transition to marriage when controlling for cohabitation, length of the assessment interval, and age. Implications are discussed in the context of prominent developmental models of marriage and current premarital interventions.     

Utility of extinction-induced response variability for the selection of mands

Functional communication training (FCT; Carr & Durand, 1985) is a commonly used differential reinforcement procedure for replacing problem behavior with socially acceptable alternative responses. Most studies in the FCT literature consist of demonstrations of the maintenance of responding when various treatment components (e.g., extinction, punishment) are present and absent (e.g., Fisher et al., 1993; Wacker et al., 1990). Relatively little research on FCT has (a) evaluated the conditions under which alternative responses are acquired or (b) described procedures with technological precision. Thus, additional research on a cogent technology for response acquisition appears to be warranted. In the current study, we evaluated the efficacy of exposing problem behavior to extinction for inducing response variability as a tool for selecting an alternative response during FCT. Once participants engaged in appropriate alternative responses, the reinforcer identified in the functional analysis as maintaining problem behavior was delivered contingent on the alternative behavior. Results showed that exposing problem behavior to extinction was a useful method for producing alternative behaviors during FCT.

Developing a short form of the IPIP Abridged Big Five-Dimensional Circumplex (AB5C) congruent with the AB5C circumplex locations

The Abridged Big-Five Dimensional Circumplex (AB5C) model stands out due to its ability to locate personality facets within a circumplex structure. However, both current measures of the AB5C model have facets inconsistent with their respective circumplex location. The current study sought to modify specific AB5C-SF scales by selecting new items for eleven facets that displayed poor psychometric properties as well as new facet labels for four facets. Although results suggested that new item selections generally improved the psychometric qualities, some specific circumplex locations remained challenging to capture. Combined with past results, this raises questions regarding whether all possible domain combinations can be well-assessed and if there are single words to capture certain trait combinations in the English language.     

New insights into the impact of digital signage as a retail atmospheric tool

This article investigates the previously little‐researched role of digital signage (DS) in retail atmospherics, using an environmental psychology framework, drawing support from the Limited Capacity Model of Mediated Message Processing (LCM). DS consists of screen displays in public spaces showing video. The method consisted of a structured questionnaires quasi‐experiment (n = 357), comparing before and after DS installation against an unchanged control mall. Results demonstrate the effectiveness of DS, which has a positive effect on shoppers' approach behaviors such as spending, mediated by perceptions of the retail environment and positive affect. Results are limited as the DS screens content was information based, whereas according to LCM, people pay more attention to emotion‐eliciting communications. The results have practical implications as DS appeals to employed shoppers. This study contributes to theory by providing a rare longitudinal environmental psychology study of the effects of an atmospheric stimulus on real shoppers in a real retail context.

Explaining inappropriate strategy selection in a simple reasoning task

People's strategy selections appear to reflect attempts to maximize performance by selecting the most effective option for a particular task or format. Theories that account for such behaviour will be named rational models of strategy selection. However, it is possible to find instances where people are apparently biased towards using less effective strategies, and such behaviour appears to go against these models. Two experiments are reported in which participants were instructed to use first one, and then the other of two possible strategies for solving a compass point directions task (the instructed phase), and were subsequently permitted to use any strategy (the free‐choice phase). A substantial minority of participants selected the less effective spatial strategy during the free‐choice phase. Overall, it was found that people who rely on the spatial strategy when given a free‐choice tend to be those who: (1) have not been given particular incentive to perform as well as possible; (2) have difficulty executing the better alternative, cancellation and (3) are particularly prone to making errors at the spatial strategy. Hence, although evidence was found in support of rational models of strategy selection, it is also suggested that these must additionally take account of the motivational and conceptual difficulties that people may have with a task.     

A Conservation of Resources Perspective on Negative Affect and Innovative Work Behaviour: the Role of Affect Activation and Mindfulness

The present study aimed to clarify the inconsistent relationship between negative affect and innovative work behaviour by taking into account the role of affect activation and mindfulness. Building on the conservation of resources theory, we hypothesized that low-activated negative affect can be associated with increased innovativeness, but only for employees with high levels of mindfulness. Conversely, high-activated negative affect is expected to have a positive, direct relationship with innovative work behaviour. Data were collected from two independent samples, namely 163 French Canadian and 101 Italian employees. Consistent with our predictions, multiple regression analysis results showed that low-activated negative affect was positively related to innovative behaviour only when mindfulness was high (vs. low), whereas high-activated negative affect was directly associated with higher innovativeness. Our findings challenge the assumption that low-activated negative affects are associated with undermined innovative behaviour, suggesting that these affective states can be related to increased innovativeness if employees are mindful. On the other hand, they support the view that high-activated negative affects provide the energizing potential for instigating innovative actions. This study is unique in examining mindfulness as a moderator that is capable of shaping the link between deactivating negative affect and employee innovativeness. As such, it answers recent calls for research on how mindfulness can contribute to workplace functioning. Moreover, this is the first study to take into account the role of activation level in the negative affect-innovative work behaviour relationship.     

Multichannel communication in normal and delinquent families

Families containing adjudicated delinquents or nondisturbed adolescents were engaged in a laboratory interaction procedure aimed at assessing inconsistent (nonredundant) verbal-nonverbal communication patterns. Detailed analyses of verbal, facial, and auditory channels indicated higher rates of positive nonverbal, negative verbal communications in control versus delinquent families and in parent-parent versus parent-child interaction. Results are discussed in terms of the potential adaptive characteristics of such positive inconsistent communications.This article is based on a doctoral dissertation submitted by the first author, under the direction of the second author, to the University of Pittsburgh.

A Neuropsychological Approach to Intelligence

This paper proposes that current psychometric intelligence tests are limited in evaluating cognitive activity. From a neuropsychological perspective, they fail to measure some fundamental cognitive abilities such as executive functions, memory, and visuospatial abilities. The analysis of the Wechsler Intelligence Scale presented shows that the original rationale for selecting the specific subtests included in the WAIS was unclear. The concept of a g factor in cognition is also analyzed, with the conclusion that the g factor continues to be controversial. The value of intelligence tests in predicting school performance is also criticized. It is proposed that the psychometric concept of general intelligence should be deleted from cognitive and neurological sciences. Finally, it is proposed that, in the future, neuropsychological instruments sensitive to more specific cognitive abilities replace current psychometric intelligence tests.     

Maintaining stereotypes in communication: Investigating memory biases and coherence-seeking in storytelling

When communicating, a general tendency exists for people to transmit more stereotype consistent (SC) than inconsistent (SI) information. Although some communicative factors have been shown to play a role, it is still not yet known the extent to which general memory biases (i.e. independent of communicative context) contribute to this phenomenon. To examine this issue, and to explore further mechanisms of the bias, the present paper presents quantitative and qualitative data of an experiment involving the transmission of a stereotype-relevant story through 20 four-person chains using the method of serial reproduction. An SC bias emerged when participants had an intention to communicate but not when they reproduced the story from memory with no such intention. Results also suggest that trying to tell a coherent story may be one further factor that contributes to the bias. These and other findings were discussed in terms of the role of communicative processes in maintaining stereotypes.     

The Selection of Multiattribute Decision Making Methods for Scholarship Student Selection

Selecting scholarship students from a number of competing candidates is a complex decision making process, in which multiple selection criteria have to be considered simultaneously. Multiattribute decision making (MADM) has proven to be an effective approach for ranking or selecting one or more alternatives from a finite number of alternatives with respect to multiple, usually conflicting criteria. This paper formulates the scholarship student selection process as an MADM problem, and presents suitable compensatory methods for solving the problem. A new empirical validity procedure is developed to deal with the inconsistent ranking problem caused by different MADM methods. The procedure aims at selecting a ranking outcome which has a minimum expected value loss, when true attribute weights are not known. An empirical study of a scholarship student selection problem in an Australian university is conducted to illustrate how the selection procedure works.     

On the Relation Between Job Characteristics and Depression: A Longitudinal Study

The current study assumes that workers actively influence the characteristics of their work environment. Not only will one's work environment (job characteristics) affect personal characteristics, such as feelings of depression; depression in turn is expected to affect the characteristics of one's work environment as well. Using a sample of 593 young Dutch workers, a longitudinal model relating feelings of depression and job characteristics to each other was tested using structural equation modeling. The results largely supported our expectations. Depressive workers were less likely to experience a job transition than non-depressive workers. If depressive workers did experience a job transition, work outcomes were less positive than for nondepressive workers. Thus, it appears that the relation between job characteristics and depression can be construed as a reciprocal relation. Implications and limitations of the study are discussed.     

The Effect of Self-Imposed Brevity on the Structure of Dyadic Communication

Differences between concise and natural communications in problem solving were investigated by comparing the communications generated by pairs of S s asked to use as few words as possible with the communications by pairs of S s of whom no such request was made. Sixteen male pairs and 16 female pairs, all undergraduate students, were tested. Two modes of communication were used: voice and teletypewriter. An analysis of message function revealed that when S s tried to be brief, they used a larger percentage of messages concerned with the exchange of information and lower percentages of messages that dealt with the rate of communication, judgments, and feedback than under the natural condition. An analysis of parts of speech revealed that those S s who restricted their communications used higher percentages of nouns and adjectives and lower percentages of pronouns, verbs, prepositions, interjections, and articles than did S s who did not restrict their communications. Most of these findings held for both modes of communication.     

Personalizing Behavioral Interventions Through Single‐Patient (N‐of‐1) Trials

Behavioral interventions are typically studied with the use of a conventional between‐subject randomized controlled trial (RCT) design. In this design, the effect of an intervention on one group of patients is compared with the effect of a control condition on another group of patients, such that a between‐subject change is tested. A between‐subject design has an underlying assumption that there is a homogenous treatment effect for a behavioral intervention, drug, or psychotherapy and that the way the intervention operates in the study will tend to operate in the same way in many other patients. We review some of the philosophical and practical problems with the use of this design when a clinician is attempting to decide on a course of behavioral treatment aimed at within‐subject change in patients who are likely to have heterogeneous or unique responses to behavioral treatment. We also review the biases inherent in our current clinical practice model, which does not use any empirical data collection or design for testing if a treatment is useful, and also in the conventional between‐subject personalized medicine RCT designs. We propose increased use of single‐patient (also known as N‐of‐1) trials that employ within‐subject designs, in cases where treatment response is heterogeneous – as is the case for most psychological and behavioral treatments. Limitations of such designs include that they can only be used when the treatment is potentially reversible, the patient can act as their own control, and the outcome can be measured repeatedly. Increased use of within‐subject trials may address in many more instances the more clinically relevant question of how a specific patient will respond to a specific treatment and could introduce a more harmonious scientific approach into the way we treat our patients. We have incorporated a case presentation that illustrates the complexities of applying evidence drawn from these different designs to selecting and evaluating treatments for the behavioral issues commonly faced by clinicians and patients.
