Predicting premeditation: future behavior is seen as more intentional than past behavior

People's intuitions about the underlying causes of past and future actions might not be the same. In 3 studies, we demonstrate that people judge the same behavior as more intentional when it will be performed in the future than when it has been performed in the past. We found this temporal asymmetry in perceptions of both the strength of an individual's intention and the overall prevalence of intentional behavior in a population. Because of its heightened intentionality, people thought the same transgression deserved more severe punishment when it would occur in the future than when it did occur in the past. The difference in judgments of both intentionality and punishment was partly explained by the stronger emotional reactions that were elicited in response to future actions than in response to past actions. We consider the implications of this temporal asymmetry for legal decision making and theories of attribution more generally.     

Unawareness is more than a chance event: comment on Lovibond and Shanks (2002)

P. F. Lovibond and D. R. Shanks (2002) suggested that expectancy of the unconditional stimulus and emotional ratings are valid indexes of awareness in Pavlovian conditioning and that participants are aware if they can discriminate the conditional stimuli. However, research suggests that processes that are irrelevant to awareness affect these measures. Further, as awareness refers to conscious experience, a valid measures needs to index subjective state rather than discrimination ability. In support, research using subjective measures has demonstrated qualitatively different effects depending on whether participants reported being aware or unaware of the stimuli. In this research, participants reported being unaware of the stimuli even though they were clearly able to discriminate the stimuli. These findings question the validity of Lovibond and Shanks' concept of awareness and their suggestion of a close association between conditioning and awareness.     

Working memory recall precision is a more sensitive index than span

Delayed adjustment tasks have recently been developed to examine working memory (WM) precision, that is, the resolution with which items maintained in memory are recalled. However, despite their emerging use in experimental studies of healthy people, evaluation of patient populations is sparse. We first investigated the validity of adjustment tasks, comparing precision with classical span measures of memory across the lifespan in 114 people. Second, we asked whether precision measures can potentially provide a more sensitive measure of WM than traditional span measures. Specifically, we tested this hypothesis examining WM in a group with early, untreated Parkinson's disease (PD) and its modulation by subsequent treatment on dopaminergic medication. Span measures correlated with precision across the lifespan: in children, young, and elderly participants. However, they failed to detect changes in WM in PD patients, either pre‐ or post‐treatment initiation. By contrast, recall precision was sensitive enough to pick up such changes. PD patients pre‐medication were significantly impaired compared to controls, but improved significantly after 3 months of being established on dopaminergic medication. These findings suggest that precision methods might provide a sensitive means to investigate WM and its modulation by interventions in clinical populations.     

Being liked is more than having a good personality: The role of matching

Is possession of desirable personality characteristics the only predictor that someone will be well-liked in a group of acquaintances, or does similarity to others in the group also matter? We tested participants (n = 844) who had been assigned to peer groups and had spent 6 weeks together. Participants assessed self and peer personalities. We found that after controlling for attributions of desirable and undesirable personality characteristics, individuals with similar personality patterns liked each other more than individuals with dissimilar patterns. Further analysis revealed similarity of basic demographic attributes (i.e., sex and race) predicted liking independent of personality similarity. Results provide a comprehensive analysis of relations between personality similarity and liking among acquaintances in a randomized, naturalistic design.     

The end point effect in autobiographical memory: more than a calendar is needed

The end point effect, an increased frequency of memories from the start and end of a period, may be due to internalised calendar representations or narrative structures. Differential predictions derived from these theories were tested in 3 studies. In Study 1, 104 students recalled 5 memories from a relationship. In Study 2, 106 students recalled 5 memories from their first term and in Study 3, 89 students recalled 3 positive and 3 negative memories from their first term. In all three studies memories were rated on phenomenology, encoding variables and rehearsal. All three studies replicated the endpoint effect, with Study 3 showing a stronger effect for positive memories. The studies showed higher rating for end point memories on phenomenology (Study 1), encoding variables (Studies 1 and 2) and rehearsal (Study 1). Generally, the results support the narrative theory and this is discussed in relation to broader theories of autobiographical memory.     

Event-method directed forgetting: Forgetting a video segment is more effortful than remembering it

Videos were presented depicting events such as baking cookies or cleaning a fish tank. Periodically, the video paused and an instruction to Remember (R) or Forget (F) the preceding video segment was presented; the video then resumed. Participants later responded more accurately to cued-recall questions (E1) and to true/false statements (E2–5) regarding R segments than F segments. This difference was larger for specific information (the woman added 3 cups of flour) than for general information (the woman added flour). Participants were also slower to detect visual probes presented following F instructions compared to those presented following R instructions. These findings suggest that intentional forgetting is an effortful process that can be performed even on segments of otherwise continuous events and that the result is a relatively impoverished representation of the unwanted information in memory.     

Harming is more intentional than helping because it is more probable: the underlying influence of probability on the Knobe effect

Knobe [2003. Intentional action and side effects in ordinary language. Analysis, 63, 190–194] demonstrated that people’s intentionality judgments in side effects depend on the outcome of the side-effect, indicating that people’s judgments of intentionality of action depend on not only the intention of the actor but also on the result of the action. However, on the basis of findings in judgment and decision making, the current study proposes another hypothesis to Knobe’s (2003) results: the participants’ intentionality judgments are related to not only the outcomes themselves but also the probabilities of outcomes predicted from the action. To test this hypothesis, the present study employed an identical experimental procedure to Knobe (2003), except that it required not only intentionality but also probability judgments for outcomes that resulted from the actions of a company president. The results replicated the findings of Knobe (2003) and showed a relationship between probability and intentionality judgment.     

Suboptimal choice by dogs: when less is better than more

The less is more effect, an example of an affect heuristic, can be shown in humans when they give greater value to a set of six baseball cards in perfect condition, than to the same set of six perfect cards together with three additional cards each with some value but in fair condition. A similar effect has been reported in monkeys which will eat both grapes and cucumbers but prefer grapes, when they prefer a single grape over a single grape plus a slice of cucumber. In the present experiment, we tested the less is more effect with a nonprimate but social species, dogs. We used dogs that would eat a slice of carrot and a slice of cheese but preferred the cheese. When we then gave them a choice between a slice of cheese and a slice of cheese plus a slice of carrot, most dogs preferred the single slice of cheese. Thus, the less is more effect appears to occur in several species.     

Processing impairments in OCD: it is more than inhibition!

The study aimed to address a significant gap in the literature on inhibition impairments in OCD, by concurrently studying facilitation and inhibition processes and the effect of threat on these twin mechanisms. Participants were 20 persons with symptomatic OCD, 11 with remitted OCD, 20 with panic disorder and 20 normal control participants. Participants were required to respond to words that were either neutral or personally threatening, which during an immediately preceding trail, were responded to as targets (facilitation) or inhibited as non-targets (inhibition). OCD participants displayed greater facilitation and reduced inhibition, differences that were related to their diagnostic status but unrelated to symptomatic status. Threat had no effect on facilitation, but exacerbated inhibition problems in the symptomatic OCD and panic groups. This research suggests that underlying differences in both facilitation and inhibition, combined with influences of activated threat-schema on inhibition may play a role in the development and maintenance of OCD.     

Imagining physically impossible self-rotations: geometry is more important than gravity

Previous studies found that it is easier for observers to spatially update displays during imagined self-rotation versus array rotation. The present study examined whether either the physics of gravity or the geometric relationship between the viewer and array guided this self-rotation advantage. Experiments 1-3 preserved a real or imagined orthogonal relationship between the viewer and the array, requiring a rotation in the observer's transverse plane. Despite imagined self-rotations that defied gravity, a viewer advantage remained. Without this orthogonal relationship (Experiment 4), the viewer advantage was lost. We suggest that efficient transformation of the egocentric reference frame relies on the representation of body-environment relations that allow rotation around the observer's principal axis. This efficiency persists across different and conflicting physical and imagined postures.     

Language is never enough: memories are more than words reveal

In this commentary I discuss the work by Fivush and Schwarzmueller (1998) including some methodological limitations to their study. It is perhaps because of these limitations that the data do not provide support for their linguistic hypothesis concerning the onset of autobiographical memory. The data do, however, address important issues in the study of autobiographical memory, particularly in terms of very long-term retention and reconstruction of unique (and perhaps distinctive) events that are pleasant. This is a welcome change from the typical studies of recall of distinctive life events in which the target event is one that revolves around unpleasant medical procedures. Future research efforts should continue along these lines, although alternative suggestions are made for which theoretical issues need to be addressed and new measures developed. © 1998 John Wiley & Sons, Ltd.     

Something more than the 'Something more than interpretation' is needed: A comment on the paper by the Process of Change Study Group

A critique is offered of the paper on non-interpretive mechanisms in psychoanalytic therapy by the Process of Change Study Group (Stern et al., 1998a). The attention paid to procedural learning and to the need to attend to implicit relational knowledge is welcomed but a number of the group's assumptions are questioned. In particular, it is argued that the differences between mother-infant and therapist-patient relationships are inadequately considered, that the polarisation of non-symbolic and verbal memory is unhelpful and that the separation of the therapy relationship into three strands is problematic. The assumption that pursuing the goal of intersubjective understanding is in itself therapeutic is questioned. It is suggested that the recognition of the importance of implicit relational knowledge calls for a wider reappraisal of important aspects of theory and practice and that direct means of making such knowledge explicit should be considered.     

Actually,a picture is worth less than 45 words: Narratives produce more false memories than photographs do

Most memory “implantation” studies have elicited false memories by using fake narratives. Recently, Wade, Garry, Read, and Lindsay (2002) showed that doctored photographs can be used to create false childhood memories in adults. Fifty percent of Wade et al.’s sample reported details of taking a childhood hot air balloon ride, although they had never been in a balloon. In this experiment, we investigated whether photos or narratives influence memory more than the other. We exposed subjects to either a fake photograph or a fake narrative of a childhood hot air balloon ride. Subjects tried to remember the false event and three real events over 1 week. Narratives were more likely to produce false memory reports than were photos. We offer a fluency-based account of our results and suggest that narratives promote more familiarity in subjects than do photographs.     

Distractor inhibition is more effective at a central than at a peripheral location

The "distractor eccentricity effect" refers to the finding of reduced interference from an incompatible distractor at a central relative to a peripheral location (Chen, 2008). The present study examines the mechanism that underlies the distractor eccentricity effect, and relates it to the inattentional blindness explored by Mack and Rock (1998), which was also more marked at a foveal than at a parafoveal location. The results suggest that these two visual phenomena may reflect the same underlying mechanism--a gradient of increasing attentional suppression from the periphery to the center.     

It is more than personal: Development and validation of a multidimensional privacy orientation scale

This study summarizes the development and validation of a multidimensional privacy orientation scale designed for measuring privacy attitudes of Social Network Site (SNS) users. Findings confirm the existence of four dimensions: (1) belief in the value of “privacy as a right”; (2) “other-contingent privacy”; (3) “concern about own informational privacy” and (4) “concern about privacy of others.” Moreover, a segmentation of SNS users based on these attitude scores reveals three types of users: (1) privacy advocates, who are concerned about both their own and other people’s privacy; (2) privacy individualists, who are concerned mostly about their own privacy, and (3) privacy indifferents, whose score on all dimensions are lower than other segments. The results indicate that the four privacy orientation dimensions and three user segments predict key differences in terms of privacy protective behavior, information disclosure, and viewing personal information of others.     

Subordinate-level categorization relies on high spatial frequencies to a greater degree than basic-level categorization

In two experiments, category verification of images of common objects at subordinate, basic, and superordinate levels was performed after low-pass spatial filtering, high-pass spatial filtering, 50% phase randomization, or no image manipulation. Both experiments demonstrated the same pattern of results: Low-pass filtering selectively impaired subordinate-level category verification, while having little to no effect on basic-level category verification. Subordinate categorization consequently relies to a greater degree on high spatial frequencies of images. This vulnerability of subordinate-level processing was specific to a lack of high spatial frequency information, as opposed to other visual information, since neither high-pass filtering nor the addition of phase noise produced a comparable reduction in performance. These results are consistent with the notion that object recognition at basic levels relies on the general shapes of objects, whereas recognition at subordinate levels relies on finer visual details.
