It was intuitive,and it felt good: a daily diary study on how people feel when making decisions

ABSTRACT

In daily life, people make plenty of decisions, either intuitively or based on analysis. So far, research has examined when decision-making leads to correct or biased outcomes. In the present study, we adopted a different perspective and explored how decision-making is associated with how people feel. In an observational study, 134 healthy participants retrospectively reported on six evenings which decisions they had made during that day (total N?=?3,850 decisions). They were also asked to indicate how they had felt before/after each decision. Multilevel regression analyses revealed that (a) people reported having felt better prior to intuitive as compared to analytical decisions, (b) people reported having felt better after as compared to before the decision, and (c) this increase in positive feeling was more pronounced for intuitive decisions. The latter two associations were robust to statistically controlling for the life domain in which the decisions occurred, the decisions’ importance and ease, and daily mood. The retrospective design and the single-item measure of mood are among the limitations of this study. Altogether, the results are in line with the idea that making everyday life decisions intuitively makes people feel good.     

Axiomatic Theories of Partial Ground I

This is part one of a two-part paper, in which we develop an axiomatic theory of the relation of partial ground. The main novelty of the paper is the of use of a binary ground predicate rather than an operator to formalize ground. This allows us to connect theories of partial ground with axiomatic theories of truth. In this part of the paper, we develop an axiomatization of the relation of partial ground over the truths of arithmetic and show that the theory is a proof-theoretically conservative extension of the theory PT of positive truth. We construct models for the theory and draw some conclusions for the semantics of conceptualist ground.     

A Longitudinal Analysis of Gaming- and Non-Gaming-Related Friendships and Social Support among Social Online Game Players

Research examining online games often focuses on their potential to negatively impact players. One of the most common concerns is that playing online with others can displace offline relationships and, consequently, detrimentally affect one’s level of “offline” social support. However, there has been little empirical evidence supporting these causal claims. The current study addresses this by outlining a longitudinal analysis between gaming- and non-gaming-related friendships and social support among a representative sample of social online players (i.e., people who play online video games with others). The results indicate that social online video game play with online or offline friends is not related to perceived social support, positively or negatively, cross-sectionally or longitudinally. Taken together, these results dispute the long-held claims of the social displacement hypothesis and instead suggest that social online video game play does not have negative real-world consequences on players’ offline friendships or levels of offline social support.     

Putting a Price tag on Healthy Behavior: The Monetary Value of Sports Participation to Individuals

This study estimates the monetary value of sports and physical activity applying the compensation variation method. While previous studies put a price tag on various health conditions, this study assigns a monetary value to healthy behavior, such as participation in sports and physical activity. Data from the German Socio-Economic Panel (1992–2013) are used for the analysis (n = 191,828). A generalized ordered response model is estimated to take the heterogeneity in the dependent variable, a single-item life satisfaction measure, into account. The results show that females (males) would be willing to forgo between €195 and €840 (€330 and €790) of their monthly net income in order to participate in sports and physical activity several times a year. A higher frequency of participation is associated with higher monetary values: females (males) are willing to forgo between €552 and €1281 (€491 and €1483) of their monthly net income to participate in sports or exercise at least once a month and between €577 and €1471 (€577 and €1662) to participate at least once a week, respectively, compared to not participating at all. Evidently, participation in sports and physical activity improves individuals’ life satisfaction and is of substantial value to individuals. The findings have implications for health economists, policy makers, and the courts. This study contributes to the literature examining the relationship between sports participation and well-being.     

Lack of free choice reveals the cost of multiple-target search within and across feature dimensions

Having to look for multiple targets typically results in switch costs. However, using a gaze-contingent eyetracking paradigm with multiple color-defined targets, we have recently shown that the emergence of switch costs depends on whether observers can choose a target or a target is being imposed upon them. Here, using a similar paradigm, we tested whether these findings generalize to the situation in which targets are specified across different feature dimensions. We instructed participants to simultaneously search for, and then fixate, either of two possible targets presented among distractors. The targets were defined as either two colors, two shapes, or one color and one shape. In one condition, only one of the two targets was available in each display, so that the choice was imposed. In the other condition, both targets would be present in each display, which gave observers free choice over what to search for. Consistent with our earlier findings, switch costs emerged when targets were imposed, whereas no switch costs emerged when target selection was free, irrespective of the dimension in which the targets were defined. The results are consistent with the operation of different modes of control in multiple-target search, with switch costs emerging whenever reactive control is required and being reduced or absent when displays allow for proactive control.     

Children's comprehension of visual formal features in television programs

A review of previous studies on children's comprehension of visual formal features did not warrant predictions about children's understanding of the formal features as used in three items from Sesamstraat, the Dutch version of Sesame Street. Therefore, a study was designed in which 45 children in the age range of 4–6 years watched the items and were interviewed. In the first item, a split screen was used to visualize simultaneity of actions. The second item used a subjective camera to suggest the construction of a home video by one of the characters. Version 1 of this item did not show the character while making home video, whereas Version 2 did show the character while filming. The third item contained a dissolve (Version 1) or a cut (Version 2) to indicate the end of a dream. A general conclusion was that although older children (mean AGE=5.9 years) understood the visual formal features better than younger children (mean AGE=4.4 years), the extent to which children in both age groups understood the visual formal features appeared to vary between items and versions. Most children in both age groups understood the split screen in the first item. The younger age group did not understand the subjective camera if the making of the home video was not shown. Both the younger and the older age group understood the version with the cut better than the original version with the dissolve. In the discussion, the question was addressed what the findings of this study and previous studies teach us about children's understanding of visual formal features in general.     

Cortical auditory disorders: a case of non-verbal disturbances assessed with event-related brain potentials

In the auditory modality, there has been a considerable debate about some aspects of cortical disorders, especially about auditory forms of agnosia. Agnosia refers to an impaired comprehension of sensory information in the absence of deficits in primary sensory processes. In the non-verbal domain, sound agnosia and amusia have been reported but are frequently accompanied by language deficits whereas pure deficits are rare. Absolute pitch and musicians' musical abilities have been associated with left hemispheric functions. We report the case of a right handed sound engineer with the absolute pitch who developed sound agnosia and amusia in the absence of verbal deficits after a right perisylvian stroke. His disabilities were assessed with the Seashore Test of Musical Functions, the tests of Wertheim and Botez (Wertheim and Botez, Brain 84, 1961, 19-30) and by event-related potentials (ERP) recorded in a modified 'oddball paradigm'. Auditory ERP revealed a dissociation between the amplitudes of the P3a and P3b subcomponents with the P3b being reduced in amplitude while the P3a was undisturbed. This is interpreted as reflecting disturbances in target detection processes as indexed by the P3b. The findings that contradict some aspects of current knowledge about left/right hemispheric specialization in musical processing are discussed and related to the literature concerning cortical auditory disorders.     

Macro-event recognition in healthy ageing,Alzheimer’s disease,and mild cognitive impairment

Event perception and cognition is integral to our everyday experience and functional ability. A commonly reported complaint in Alzheimer’s disease (AD) is the inability to follow narratives – be it textual, conversational, video, or pictures. This phenomenon has received little systematic research so far. In the current study, we developed a novel paradigm to examine macro-event recognition in individuals with AD in the early stage and its preceding stage of mild cognitive impairment (MCI) in comparison with cognitively healthy older adults, using pictures depicting events. In Experiment 1, we examined participants’ ability to integrate pictorially depicted sub-events into macro-events. The pictures were presented in a scrambled order, and participants were expected to arrange them in the temporally and causally appropriate sequence, as dictated by the macro-event schema. Additionally, we investigated the effect of cueing the appropriate event schema by providing a word cue (verb). In Experiment 2, macro-event recognition was examined again using a cognitively less taxing paradigm, where pictures depicting sub-events were presented in correct order, but staggered, and recognition speed was measured. We observed significant deficits in the AD and MCI groups’ performance compared with the cognitively healthy older adults, across both experiments, suggesting event perception and cognition is impaired early in the course of AD. There was no effect of cueing on the performance of any of the groups. The theoretical and clinical implications of these findings are discussed.     

Some studies on the internal structure of propositions

Summary Five experiments were carried out to test the information processing of the propositional arguments instrument and beneficiary. Proceeding from the assumption that propositions are basic units of memory, it was hypothesized that instrument and beneficiary would show different effects in recall experiments, depending on whether they were components of appropriate propositions or not. Experiments I and II were conducted to test this assumption. The results showed that things are more complicated than was expected. Besides propositional structure, the semantic integration of concrete propositions has to be taken into account to predict their psychological processing. Experiments III, IV, and V were conducted to prove this. On the whole, it was found that instruments can always be considered as arguments but beneficiaries only when they are obligatory; and further that in general instrument arguments are semantically more strongly implied by their predicates than beneficiary arguments are.I would like to thank Trevor Scott for his help in writing the English text.
