The Paradoxes of Humor and the Burdens of Despair

SUMMARY

People today often express considerable despair about old age and the aging process. Older adults who experience frequent losses of connections with important persons can feel considerable despair in old age. Nevertheless, many older people retain hope in the face of situations that elicit despair and demonstrate what gerontologists call the “paradox of well being” in later life. Often, their hope is expressed in humor. This paper traces the connections among humor, hope, and religious faith in older adults. It argues that even persons who suffer from dementia can continue to express what Viktor Frankl called the “defiant power of the human spirit” through their humor.

Inaction inertia

Inaction inertia occurs when bypassing an initial action opportunity has the effect of decreasing the likelihood that subsequent similar action opportunities will be taken. This overview of the inaction inertia literature demonstrates the impact of inaction inertia on decision making. Based on research on the causes of inaction inertia, we show that it is a multi-determined phenomenon, explained by both valuation and regret considerations. Moreover, we demonstrate how a sour grapes explanation of inaction inertia might integrate these two accounts. Furthermore, we explain when inaction inertia is most likely to occur and how it can be prevented. We conclude that the inaction inertia literature does not only add to our understanding of this intriguing phenomenon, but also contributes to related social psychological phenomena, such as the sunk cost effect, sequential decision making, decision avoidance (e.g., choice deferral, status quo bias, decisional conflict), and procrastination.     

Multicriteria Optimization Technique for Optimal Design of Orthotropic Bridges

The design improvement of large‐scale structures such as cable stayed and suspension bridges with large spans is one of the major engineering optimization problems faced by design engineers. In many real‐life engineering design problems, it is necessary to carry out large‐scale experimental physical models for only one prototype to construct the feasible solution set that is too expensive and not practical. For these reasons, an experimental search for optimal solutions is often not carried out at all. This paper presents a technique for multicriteria analysis, which involve the finite element analysis of the prototype in the optimization process. The improvement of the Suez Canal Bridge in Egypt is introduced as a real‐life large‐scale case study. The parameter space investigation method, the visual basic for application programming language, and Femap as finite element analysis software provide an implementation tools to construct the feasible and Pareto solution sets for the studied bridge. An efficient combination between the parameter space investigation method and the finite element programme was successfully investigated to obtain the Pareto solution set. This study shows possibility to apply the multicriteria optimization method for more applications on different large‐scale structural systems in the future.

Sadness and consumption

Sadness influences consumption, leading individuals to pay more to acquire new goods and to eat more unhealthy food than they would otherwise. These undesirable consumption effects of sadness can occur without awareness, thus representing more than just conscious attempts at “retail therapy.” In an experiment with real food consumption, the present paper examines the hypothesis that sadness' impact on consumption could be attenuated if the choice context counteracted appraisals of helplessness and enhanced a sense of individual control. Results revealed that: (1) sadness elevates self-reports of helplessness in response to the emotion-inducing situation, (2) helplessness mediates the sadness–consumption effect, and (3) inducing a sense of control (via choice) attenuates sadness' effect.     

The presence of threat affects saccade trajectories

In everyday life, fast identification and processing of threat-related stimuli is of critical importance for survival. Previous studies suggested that spatial attention is automatically allocated to threatening stimuli, such as angry faces. However, in the previous studies the threatening stimuli were not completely irrelevant for the task. In the present study we used saccadic curvature to investigate whether attention is automatically allocated to threatening emotional information. Participants had to make an endogenous saccade up or down while an irrelevant face paired with an object was present in the periphery. The eyes curved away more from the angry faces than from either neutral or happy faces. This effect was not observed when the faces were inverted, excluding the possible role of low-level differences. Since the angry faces were completely irrelevant to the task, the results suggest that attention is automatically allocated to the threatening stimuli, which generates activity in the oculomotor system, and biases behaviour.     

Anger superiority effect: The importance of dynamic emotional facial expressions

A rapid response to a threatening face in a crowd is important to successfully interact in social environments. Visual search tasks have been employed to determine whether there is a processing advantage for detecting an angry face in a crowd, compared to a happy face. The empirical findings supporting the “anger superiority effect” (ASE), however, have been criticized on the basis of possible low-level visual confounds and because of the limited ecological validity of the stimuli. Moreover, a “happiness superiority effect” is usually found with more realistic stimuli. In the present study, we tested the ASE by using dynamic (and static) images of realistic human faces, with validated emotional expressions having similar intensities, after controlling the bottom-up visual saliency and the amount of image motion. In five experiments, we found strong evidence for an ASE when using dynamic displays of facial expressions, but not when the emotions were expressed by static face images.     

Angry faces hold the eyes

Efficient processing of complex social and biological stimuli associated with threat is crucial for survival. Previous studies have suggested that threatening stimuli such as angry faces not only capture visual attention, but also delay the disengagement of attention from their location. However, in the previous studies disengagement of attention was measured indirectly and was inferred on the basis of delayed manual responses. The present study employed a novel paradigm that allows direct examination of the delayed disengagement hypothesis by measuring the time it takes to disengage the eyes from threatening stimuli. The results showed that participants were indeed slower to make an eye movement away from an angry face presented at fixation than from either a neutral or a happy face. This finding provides converging support that the delay in disengagement of attention is an important component of processing threatening information.     

Target–target similarity and the attentional blink: Task-relevance matters!

Studies of the attentional blink (AB) indicate that similarity modulates the magnitude of the impairment in reporting the second of two masked targets. The present experiments tested whether similarity-based modulations of the AB are determined by all object dimensions or by task-relevant dimensions only. Similarity between target faces was manipulated on two dimensions, only one of which was task relevant. The results indicated that similarity on the task-relevant dimension modulated the AB, whereas similarity on task-irrelevant dimension did not. These results suggest that selection during the AB can occur on the level of task-relevant dimensions.     

Face aftereffects suggest interdependent processing of expression and sex and of expression and race

Bruce and Young (1986) proposed that functionally different aspects of faces (e.g., sex, identity, and expression) are processed independently. Although interdependent processing of identity and expression and of identity and sex have been demonstrated previously, evidence for interdependent processing of sex and expression is equivocal. Using a visual adaptation paradigm, we show that expression aftereffects can be simultaneously induced in different directions along anger–fear continua for male and female faces (Experiment 1) and for East Asian and Black African faces (Experiment 2). These findings for sex- and race-contingent expression aftereffects suggest that processing of expression is interdependent with processing of sex and race and are therefore problematic for models of face perception that have emphasized independent processing of functionally different aspects of faces. By contrast, our findings are consistent with models of face processing that propose that invariant physical aspects of faces and changeable social cues can be processed interdependently.
