Role of Interactivity in Learning from Engineering Animations

This study examines the pedagogic value of incorporating sophisticated interactivity features into lessons on hand‐held devices. Engineering students (Experiment 1) and non‐engineering college students (Experiment 2) spent 5 min studying an animation showing a six‐step maintenance procedure for a mechanical device called a Power Take‐Off presented on an iPad. In both experiments, students who received high interactivity (i.e., rotation through dragging movements and zoom through pinching movements) reported higher interest but did not show better learning as compared to the low interactivity group (i.e., pause and continue buttons on the touch screen) or no interactivity group. Across two experiments, the interactivity hypothesis was supported in terms of increased interest but not supported in terms of improved learning. Thus, there was not support for the idea that increasing situational interest through high levels of interactivity primes deeper learning processes that produce better learning outcomes.

When the brain simulates stopping: Neural activity recorded during real and imagined stop-signal tasks

It has been suggested that mental rehearsal activates brain areas similar to those activated by real performance. Although inhibition is a key function of human behavior, there are no previous reports of brain activity during imagined response cancellation. We analyzed event-related potentials (ERPs) and time–frequency data associated with motor execution and inhibition during real and imagined performance of a stop-signal task. The ERPs characteristic of stop trials—that is, the stop-N2 and stop-P3—were also observed during covert performance of the task. Imagined stop (IS) trials yielded smaller stop-N2 amplitudes than did successful stop (SS) and unsuccessful stop (US) trials, but midfrontal theta power similar to that in SS trials. The stop-P3 amplitude for IS was intermediate between those observed for SS and US. The results may be explained by the absence of error-processing and correction processes during imagined performance. For go trials, real execution was associated with higher mu and beta desynchronization over motor areas, which confirms previous reports of lower motor activation during imagined execution and also with larger P3b amplitudes, probably indicating increased top-down attention to the real task. The similar patterns of activity observed for imagined and real performance suggest that imagination tasks may be useful for training inhibitory processes. Nevertheless, brain activation was generally weaker during mental rehearsal, probably as a result of the reduced engagement of top-down mechanisms and limited error processing.     

Improving Psychological Measurement: Does It Make a Difference? A Comment on Nesselroade and Molenaar (2016)

Nesselroade and Molenaar advocate the use of an idiographic filter approach. This is a fixed-effects approach, which may limit the number of individuals that can be simultaneously modeled, and it is not clear how to model the presence of subpopulations. Most important, Nesselroade and Molenaar's proposal appears to be best suited for modeling long time series on a few variables for a few individuals. Long time series are not common in psychological applications. Can it be applied to the usual longitudinal data we face? These are characterized by short time series (four to five points in time), hundreds of individuals, and dozens of variables. If so, what do we gain? Applied settings most often involve between-individual decisions. I conjecture that their approach will not outperform common, simpler, methods. However, when intraindividual decisions are involved, their approach may have an edge.     

There’s More Than Catastrophizing in Chronic Pain: Low Frustration Tolerance and Self-Downing Also Predict Mental Health in Chronic Pain Patients

Among the potential range of irrational beliefs that could be used as predictors of physical and mental health, catastrophizing is the process that has received most attention in chronic pain research. Other irrational processes such as demandingness, low frustration tolerance, and self-downing have rarely been studied. The goal of this study was to explore whether this wider range of beliefs is associated with health in chronic pain patients beyond catastrophizing. A total of 492 chronic pain patients completed a measure of irrational beliefs, a measure of physical and mental health, and a numerical rating scale designed to assess pain intensity and interference. Irrational processes were more strongly associated with mental than with physical health. Low frustration tolerance and self-downing were found to be significantly related to mental health even after controlling for the effect of catastrophizing. Processes other than catastrophizing appear to have potentially important relationships with the mental health of people with chronic pain. These results may offer new intervention targets for practitioners.     

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.     

Uncovering unknown unknowns: Towards a Baconian approach to management decision-making

Bayesian decision theory and inference have left a deep and indelible mark on the literature on management decision-making. There is however an important issue that the machinery of classical Bayesianism is ill equipped to deal with, that of “unknown unknowns” or, in the cases in which they are actualised, what are sometimes called “Black Swans”. This issue is closely related to the problems of constructing an appropriate state space under conditions of deficient foresight about what the future might hold, and our aim is to develop a theory and some of the practicalities of state space elaboration that addresses these problems. Building on ideas originally put forward by Bacon (1620), we show how our approach can be used to build and explore the state space, how it may reduce the extent to which organisations are blindsided by Black Swans, and how it ameliorates various well-known cognitive biases.     

High Trait Cheerfulness Individuals are More Sensitive to the Emotional Environment

The aim of this paper was to study whether trait cheerfulness modulates changes in state cheerfulness as a result of exposing participants to affective stimuli. Two studies with a within-participant experimental design were carried out. Forty-eight (33 women) and sixty-four (45 women) undergraduate psychology students were selected as Sample 1 and Sample 2, respectively, for scoring high or low on the Trait Form of the State-Trait-Cheerfulness Inventory (STCI-T; Ruch et al. in Humor Int J Humor Res 9:303–339, 1996; Ruch et al. in Personal Individ Differ 22:477–491, 1997). Participants watched amusing, neutral, and sad film clips and reported their affective states before and after viewing them. In the second study, heart rate and skin conductance level were also recorded. Results showed that people with high trait cheerfulness reported greater changes in state cheerfulness when exposed to both amusing and sad film clips, showing larger increases and decreases in state cheerfulness, respectively, than participants with low trait cheerfulness. Effects were not mediated by social desirability. Furthermore, people with low trait cheerfulness showed a greater heart rate deceleration during the visioning of the clips compared to high trait cheerfulness participants, especially in an amusing scene with high emotional load. No modulation on trait cheerfulness was found for skin conductance level. Data with self-report and electrophysiological measures are discussed, highlighting that high trait cheerfulness people are more permeable to affective events, perhaps showing a better understanding and management of them.     

Procura-PALavras (P-PAL): A Web-based interface for a new European Portuguese lexical database

In this article, we present Procura-PALavras (P-PAL), a Web-based interface for a new European Portuguese (EP) lexical database. Based on a contemporary printed corpus of over 227 million words, P-PAL provides a broad range of word attributes and statistics, including several measures of word frequency (e.g., raw counts, per-million word frequency, logarithmic Zipf scale), morpho-syntactic information (e.g., parts of speech [PoSs], grammatical gender and number, dominant PoS, and frequency and relative frequency of the dominant PoS), as well as several lexical and sublexical orthographic (e.g., number of letters; consonant–vowel orthographic structure; density and frequency of orthographic neighbors; orthographic Levenshtein distance; orthographic uniqueness point; orthographic syllabification; and trigram, bigram, and letter type and token frequencies), and phonological measures (e.g., pronunciation, number of phonemes, stress, density and frequency of phonological neighbors, transposed and phonographic neighbors, syllabification, and biphone and phone type and token frequencies) for ~53,000 lemmatized and ~208,000 nonlemmatized EP word forms. To obtain these metrics, researchers can choose between two word queries in the application: (i) analyze words previously selected for specific attributes and/or lexical and sublexical characteristics, or (ii) generate word lists that meet word requirements defined by the user in the menu of analyses. For the measures it provides and the flexibility it allows, P-PAL will be a key resource to support research in all cognitive areas that use EP verbal stimuli. P-PAL is freely available at http://p-pal.di.uminho.pt/tools.     

Effects of Bilingual Tact Instruction for a Child with Communication Disorder

We evaluated the effects of tact training when instruction was presented in English only compared to tact training in a bilingual format (in English and the home language, Portuguese) for a participant diagnosed with a communication disorder. The participant’s parents completed a questionnaire describing his exposure to both languages prior to the start of the study. We also conducted formal language assessments to determine the participant’s preexisting language abilities. An adapted alternating treatment design was used to compare the rate of acquisition in the two training conditions. Results show the participant emitted more correct responses during tact training in English than during the bilingual tact training. Generalization and maintenance of acquired tact responses for stimuli trained in the bilingual condition were greater than for stimuli trained in the English-only condition. These results are discussed with respect to implications for language-training programs for children with language delays and developmental disabilities, and we outline suggestions for future research in this area.
