What day is today? A social-psychological investigation into the process of time orientation.

Social-psychological research on time has pointed to the social construct of time rather than a mere physical entity that we reflect cognitively. Using two paradigms (day retrieval process and goal priming), the authors show that the time orientation is strongly prone to social influences and argue that a self-regulatory process underlies these findings. The degree of social comparison orientation in Study 1 and the degree of identification with groups for which the landmark is relevant (Study 2) both moderate the functionality of the landmarks within time orientation. Consistent with these findings, Studies 3 and 4 offer evidence that the activation of a personally relevant goal activates the day of goal attainment, a process that again can be moderated by social comparison orientation and identification. Overall, these results suggest a socially regulated time orientation. The internal clock (if any) is at least partly a "social clock."     

Spacing and the transition from calculation to retrieval

Many arithmetic problems can be solved in two ways—by a calculation involving several steps and by direct retrieval of the answer. With practice on particular problems, memory retrieval tends to supplant calculation—an important aspect of skill learning. We asked how the distribution of practice on particular problems affects this kind of learning. In two experiments, subjects repeatedly worked through sets of multiple-digit multiplication problems. The size of the trained problem set was varied. Using a smaller set size (with shorter average time between problem repetitions) showed faster responses and an earlier transition to retrieval during training. However, in a test session presented days later, the pattern reversed, with faster responses and more retrieval for the large set size. Evidently, maximizing the occurrence of direct retrieval within training is not the best way to promote learning to retrieve the answer. Practical implications are discussed.     

Comparison of chemosensory, auditory and visual event-related potential amplitudes

To enhance understanding of neuropsychological processing underlying chemosensory event-related potentials (CSERPs), the objective of the present study was to compare CSERPs with auditory (AERPs) and visual event-related potentials (VERPs), and to approach the question of similarities in neuropsychological processing by means of correlation and cluster analyses. A multisensory ERP protocol was used, in which olfactory/chemosomatosensory (pyridine), auditory (1000-Hz tone) and visual (white circle) stimuli were presented in a pseudo-randomized sequence to 18 young, healthy adults. The results show (1) a morphological relation between P2 and P3 components that is different for the chemosensory than for the auditory and visual modalities, (2) a relatively weak association between the chemosensory and auditory/visual modalities for P3 in terms of both correlation and cluster, and (3) a P2/P3 cluster for the chemosensory but not auditory or visual modality. This supports the claim that the chemosensory P2 and P3 components reflect similar neuropsychological processes.     

A plea for pragmatics

Let intentionalism be the view that what proposition is expressed in context by a sentence containing indexicals depends on the speaker’s intentions. It has recently been argued that intentionalism makes communicative success mysterious and that there are counterexamples to the intentionalist view in the form of cases of mismatch between the intended interpretation and the intuitively correct interpretation. In this paper, I argue that these objections can be met, once we acknowledge that we may distinguish what determines the correct interpretation from the evidence that is available to the audience, as well as from the standards by which we judge whether or not a given interpretation is reasonable. With these distinctions in place, we see that intentionalism does not render communicative success mysterious, and that cases of mismatch between the intended interpretation and the intuitively correct one can easily be accommodated. The distinction is also useful in treating the Humpty Dumpty problem for intentionalism, since it turns out that this can be treated as an extreme special case of mismatch.     

Infants’ developing expectations of possible and impossible tool-use events between ages 8 and 12 months

Infants’ developing causal expectations for the outcome of a simple tool-use event from ages 8 to 12 months were investigated. Causal expectations were studied by comparing infants’ developing tool-use actions (i.e. as tool-use agents) with their developing perceptual reactions (i.e. as tool-use observers) to possible and impossible tool-use events. In Experiment 1, tool-use actions were studied by presenting infants, ages 8 and 12 months, with tool-use object-retrieval problems. In Experiment 2, a second age-matched sample of infants watched a comparable series of possible and impossible tool-use events in which a tool was used to retrieve a goal-object. Two core related findings were made. First, infants’ causal action and causal perception develop in parallel. In both action and perception, supporting tool-use develops before surrounding tool-use. Second, infants’ tool-use action develops before their causal perception of comparable tool-use events. The findings support the constructivist hypothesis that infants’ causal actions may develop before and inform their causal perceptions.     

Measures of national stereotypes as predictors of the latencies of inductive versus deductive stereotypic judgements

According to Taifel's accentuation theory, national stereotypes can be thought of as the correlation between trait dimensions and national affiliations, This correlation is high when the trait shows high homogeneity within and high distinctiveness between the national groups. The present study tested the hypothesis that a trait's distinctiveness would facilitate inductive stereotypic judgements (inferences from trait to nationality) whereas homogeneity would facilitate deductive stereotypic judgements (inferences from nationality to trait). The latencies of inductive and deductive stereotypic judgements of 48 German subjects were assessed for 39 traits and three foreign nationalities (English, French, Italian). Multiple regression analyses using latencies for both types of judgements us criterion variables and both distinctiveness and homogeneity as predictor variables were conducted. The stereotype measures of Katz and Braly and McCauley and Stitt served as additional predictor variables. As expected from accentuation theory, distinctiveness predicted inductive but not deductive latencies, whereas homogeneity predicted deductive but not inductive latencies. For the latencies of deductive stereotypic judgements, the stereotype measure of Katz and Braly as well as that of McCauley and Stitt also proved to be significant predictors. The results are discussed and recommendations are given with respect to the assessment of national stereotypes.     

Cutaneous saltation within and across arms: a new measure of the saltation illusion in somatosensation

A new objective procedure was used to measure the strength of cutaneous saltation, in order to clarify current debates about the nature of this illusion. Three taps were presented successively to three possible forearm locations. Participants attended to the middle location and reported whether a tap was perceived there. When all stimuli were delivered to the same arm and intertap intervals were short, participants were unable to distinguish real and illusory stimuli at the middle location. When both arms were stimulated, location judgments on one arm were shifted toward a tap subsequently delivered to the other arm. These results challenge the view that saltation is a purely attentional phenomenon, but they are inconsistent with the idea that this illusion is produced in the primary somatosensory cortex.     

Asymmetrical friendships? People are willing to risk COVID-19 infection from friends but are reluctant to pass it on to them

Although most protective behaviors related to the COVID-19 pandemic come with personal costs, they will produce the largest benefit if everybody cooperates. This study explores two interacting factors that drive cooperation in this tension between private and collective interests. A preregistered experiment (N = 299) examined (a) how the quality of the relation among interacting partners (social proximity), and (b) how focusing on the risk of self-infection versus onward transmission affected intentions to engage in protective behaviors. The results suggested that risk focus was an important moderator of the relation between social proximity and protection intentions. Specifically, participants were more willing to accept the risk of self-infection from close others than from strangers, resulting in less caution toward a friend than toward a distant other. However, when onward transmission was the primary concern, participants were more reluctant to effect transmission to close others, resulting in more caution toward friends than strangers. These findings inform the debate about effective nonclinical measures against the pandemic. Practical implications for risk communication are discussed.
