Laughter and Stress in Daily Life: Relation to Positive and Negative Affect

The present study investigated the proposal that increased laughter can serve to moderate the affective impact of negative life events. Community participants kept a record of their actual frequency of laughter for a 3-day period, and completed a measure of stressful life events each evening. Current levels of positive and negative affect were also obtained in the morning and evening of each day. A series of simple correlations, computed on a daily basis, provided little evidence for any direct relationships between amount of daily laughter and either positive or negative affect. Instead, more complex moderator analyses revealed that greater negative affect was clearly associated with a higher number of stressful life events, but only for those individuals with a lower frequency of actual laughter. In contrast, and in support of a stress buffering hypothesis, it was found that individuals with a higher frequency of laughter did not show greater levels of negative affect as stressful life events increased. When considering positive affect, it was found that only males showed a significant moderating effect of laughter. For males who laughed more frequently, a greater number of stressful life events was associated with higher levels of positive affect. These findings are discussed in terms of several possible mechanisms which may account for the moderating effects of laughter on affect, including the use of cognitive appraisals and emotion-focused coping strategies.     

Not All Alike: The Distinctive Impact of Voluntary and Involuntary Effort on Stress and Fatigue

Nowadays, little evidence exists on how variations in effort affect worker health, such as stress and fatigue, two important and undesirable outcomes for workers. Then, this paper analyses the impact of different dimensions of effort on stress and fatigue. To do so we use past literature to links the different effort dimensions on employee health. Concretely, the frameworks used in the paper are the one developed by Karasek and Theorell (1990), according to which the different combinations of work demands, competences in decision making and social support determine the stress employees suffer; and the effort-reward imbalance model (ERI Model) of Siegrist (Psychology 1:27–41, 1996). This provides a more sensitive model of stress, as it uses a combination of extrinsic effort and intrinsic effort as predictors of stress. Building on these theoretical models of job stress we argue that one main source of employee stress and fatigue is employee effort. Using a representative Spanish data set, our study reveals that different dimensions of effort have different consequences for workers. Whereas involuntary effort increases both stress and fatigue, voluntary effort entails a decrease in both.     

Implicit but Not Explicit Affectivity Predicts Circadian and Reactive Cortisol: Using the Implicit Positive and Negative Affect Test

ABSTRACT Self-report measures assess mental processes or representations that are consciously accessible. In contrast, implicit measures assess automatic processes that often operate outside awareness. Whereas self-report measures have often failed to show expected relationships with endocrine stress responses, little effort has been made to relate implicit measures to endocrine processes. The present work examines whether implicit affectivity as assessed by the Implicit Positive and Negative Affect Test (IPANAT) predicts cortisol regulation. In Study 1 , implicit low positive affectivity, but not negative affectivity, significantly predicted circadian cortisol release. In Study 2 , implicit negative affectivity, but not positive affectivity, significantly predicted the cortisol response to acute stress. By contrast, cortisol regulation was not predicted by self-reported affectivity. The findings support the use of implicit affectivity measures in studying individual differences in endocrine stress responses and point to a differential role of positive and negative affectivity in baseline versus stress-contingent cortisol release, respectively.     

Doing Good at Work Feels Good at Home,but Not Right Away: When and Why Perceived Prosocial Impact Predicts Positive Affect

When and why does the experience of helping others at work spill over into positive affect at home? This paper presents a within‐person examination of the association between perceived prosocial impact at work and positive affect at home, as well as the psychological mechanisms that mediate this relationship. Sixty‐eight firefighters and rescue workers completed electronic diaries twice a day over the course of 1 working week. Random‐coefficient modeling showed that perceived prosocial impact predicted positive affect at bedtime. This relationship was mediated by perceived competence at the end of the working day and positive work reflection during after‐work hours but not by positive affect at the end of the working day. The findings demonstrate that the experience of helping others at work has delayed emotional benefits at home that appear to be channeled through the cognitive mechanisms of perceived competence and reflection rather than through an immediate affective boost.     

All Negative Moods Are Not Equal: Motivational Influences of Anxiety and Sadness on Decision Making

Affective states of the same valence may have distinct, yet predictable, influences on decision processes. Results from three experiments show that, in gambling decisions, as well as in job-selection decisions, sad individuals are biased in favor of high-risk/high-reward options, whereas anxious individuals are biased in favor of low-risk/low-reward options. We argue that these biases occur because anxiety and sadness convey distinct types of information to the decision-maker and prime different goals. While anxiety primes an implicit goal of uncertainty reduction, sadness primes an implicit goal of reward replacement. We offer that these motivational influences operate through an active process of feeling monitoring, whereby anxious or sad individuals think about the options and ask themselves, “What would I feel better about …?”     

Not All Visual Expertise Is Holistic, but It May Be Leftist: The Case of Chinese Character Recognition

ABSTRACT— We examined whether two purportedly face-specific effects, holistic processing and the left-side bias, can also be observed in expert-level processing of Chinese characters, which are logographic and share many properties with faces. Non-Chinese readers (novices) perceived these characters more holistically than Chinese readers (experts). Chinese readers had a better awareness of the components of characters, which were not clearly separable to novices. This finding suggests that holistic processing is not a marker of general visual expertise; rather, holistic processing depends on the features of the stimuli and the tasks typically performed on them. In contrast, results for the left-side bias were similar to those obtained in studies of face perception. Chinese readers exhibited a left-side bias in the perception of mirror-symmetric characters, whereas novices did not; this effect was also reflected in eye fixations. Thus, the left-side bias may be a marker of visual expertise.     

Unpacking Response Contingent Positive Reinforcement: Reward Probability,but Not Environmental Suppressors,Prospectively Predicts Depressive Symptoms via Behavioral Activation

Behavioral models of depression conceptualize the development and maintenance of depressive symptoms as occurring within a system of response-contingent positive reinforcement (RCPR). Such models propose a negative cycle in which a decrease in positive reinforcement of adaptive, approach-oriented behaviors (i.e., RCPR) results in reduced behavioral activation and increased depressive symptoms, which in turn feeds back into further decreases in positive reinforcement and maintains the cycle. Previous research indicates that RCPR has two lower-order constructs, reward probability and environmental suppressors. The present study evaluated a hypothesized mediational model in which the paths from each of the two domains of RCPR to depressive symptoms are mediated by behavioral activation. The sample consisted of 150 college students (78.0% women), ranging in age from 18 to 47 years (M = 20.81, SD = 3.96), who endorsed moderate to severe depressive symptoms at a baseline (time 1) evaluation. Findings from a path analysis provide support for the mediated path between reward probability at time 1 and depressive symptoms at time 3, via behavioral activation at time 2. In contrast, environmental suppressors at time 1 demonstrated a direct impact on depressive symptoms at time 3, and this relationship was not mediated by behavioral activation at time 2. These findings provide a partial test of behavioral frameworks and provide evidence of separate pathways between domains of RCPR and depressive symptoms.
