The world is not flat: can people reorient using slope?

Studies of spatial representation generally focus on flat environments and visual input. However, the world is not flat, and slopes are part of most natural environments. In a series of 4 experiments, we examined whether humans can use a slope as a source of allocentric, directional information for reorientation. A target was hidden in a corner of a square, featureless enclosure tilted at a 5° angle. Finding it required using the vestibular, kinesthetic, and visual cues associated with the slope gradient. In Experiment 1, the overall sample performed above chance, showing that slope is sufficient for reorientation in a real environment. However, a sex difference emerged; men outperformed women by 1.4 SDs because they were more likely to use a slope-based strategy. In Experiment 2, attention was drawn to the slope, and participants were prompted to rely on it to solve the task; however, men still outperformed women, indicating a greater ability to use slope. In Experiment 3, we excluded the possibility that women's disadvantage was due to wearing heeled footwear. In Experiment 4, women required more time than men to identify the uphill direction of the slope gradient; this suggests that, in a bottom-up fashion, a perceptual or attentional difficulty underlies women's disadvantage in the ability to use slope and their decreased reliance on this cue. Overall, a bi-coordinate representation was used to find the goal: The target was encoded primarily with respect to the vertical axis and secondarily with respect to the orthogonal axis of the slope.

Learning to fear outgroups: An associative learning explanation for the development and reduction of intergroup anxiety

Pavlovian conditioning is a form of associative learning shown to contribute to the development and reduction of clinical anxiety and fear, and more recently, intergroup anxiety and fear. The current review provides a synthesis of the literature on associative learning of fear toward outgroups. Findings are reviewed that outline how fear toward the outgroup, relative to the ingroup, can be preferentially learnt and is resistant to extinction‐based techniques. Novel future research directions for intergroup anxiety are then identified based upon previous research on clinical anxiety. It is proposed that processes known to enhance the extinction of specific phobia should be investigated with social stimuli. Specifically, it is argued that exploring cognitive factors during extinction and conducting extinction in multiple contexts may provide new avenues to pursue intergroup harmony through reduced intergroup anxiety. The review concludes by suggesting innovative research designs are needed to validate an associative learning account of fear toward outgroups outside of experimental settings.     

Being the agent: memory for action events

Whoever paid the bill at the restaurant last night, will clearly remember doing it. Independently from the type of action, it is a common experience that being the agent provides a special strength to our memories. Even if it is generally agreed that personal memories (episodic memory) rely on separate neural substrates with respect to general knowledge (semantic memory), little is known on the nature of the link between memory and the sense of agency. In the present paper, we review results from two experiments investigating the effects of agency on both explicit and implicit memory traces. Performance of normal subjects is compared to that of schizophrenic patients in order to explore the role of awareness of action on memory. It is proposed that reliable first-person information is necessary to create a stable and coherent motor memory trace.

“Metaphysische Ergebnisse”: Phenomenology and Metaphysics in Edmund Husserl’s <Emphasis Type="Italic">Cartesianische Meditationen</Emphasis> (§60). Attempt at Commentary

The main goal of the present paper is to offer a preliminary study of the relations between phenomenology and metaphysics in Husserl. After a brief presentation of what Husserl means by the term “metaphysics”, the rest of our research will consist of a detailed commentary on §60 of the Cartesian Meditations (Metaphysische Ergebnisse unserer Auslegung der Fremderfahrung). Our aim is to explain in what sense, according to Husserl, the “outcomes” of the phenomenological constitution of monadological intersubjectivity entail the solution to a traditional metaphysical problem, i.e., that of the existence of just one real world. The present investigation does not pretend to be more than an introduction. Besides shedding some light on a specific text, it will pave the way for a future inquiry into the relations between phenomenology and metaphysics in Husserl.     

Divided attention enhances the recognition of emotional stimuli: evidence from the attentional boost effect

The present study examined predictions of the early-phase-elevated-attention hypothesis of the attentional boost effect (ABE), which suggests that transient increases in attention at encoding, as instantiated in the ABE paradigm, should enhance the recognition of neutral and positive items (whose encoding is mostly based on controlled processes), while having small or null effects on the recognition of negative items (whose encoding is primarily based on automatic processes). Participants were presented a sequence of negative, neutral and positive stimuli (pictures in Experiment 1, words in Experiment 2) associated to target (red) squares, distractor (green) squares or no squares (baseline condition). They were told to attend to the pictures/words and simultaneously press the spacebar of the computer when a red square appeared. In a later recognition task, stimuli associated to target squares were recognised better than stimuli associated to distractor squares, replicating the standard ABE. More importantly, we also found that: (a) the memory enhancement following target detection occurred with all types of stimuli (neutral, negative and positive) and (b) the advantage of negative stimuli over neutral stimuli was intact in the DA condition. These findings suggest that the encoding of negative stimuli depends on both controlled (attention-dependent) and automatic (attention-independent) processes.     

Direct and indirect intergroup friendship effects: testing the moderating role of the affective-cognitive bases of prejudice

Direct friendship with outgroup members and the knowledge of ingroup-outgroup friendships (indirect friendship) can both reduce outgroup prejudice. Three correlational studies (Ns = 338, 141, and 798) tested the moderating role of the affective-cognitive bases of prejudice, assessing whether the size of the friendship- prejudice relationship depends on the extent to which emotions (vs. thoughts) are relevant to the prejudiced attitudes at stake. In Study 1, direct friendship effects were larger with outgroups generating stronger affective responding than with outgroups generating stronger cognitive responding, whereas indirect friendship effects were larger with cognitive than with affective outgroups. Study 2 detected a similar pattern but with prejudice basis assessed in terms of individual differences. Study 3 replicated Study 2's indirect friendship-cognitive basis moderation in a context of historically polarized intergroup relations and on two new outcome variables, intergroup trust and negative action tendencies.     

Accountability moderates member-to-group generalization: Testing a dual process model of stereotype change

According to contemporary models of accountability [Lerner, J.S., & Tetlock, P.E. (1999). Accounting for the effects of accountability. Psychological Bulletin, 125, 255-275], when individuals are warned that they will be held accountable for their decisions, both information processing and judgment vigilance increase. We used an established generalization paradigm [Garcia-Marques, L., & Mackie, D.M. (1999). The impact of stereotype incongruent information on perceived group variability and stereotype change. Journal of Personality and Social Psychology, 77, 979-990] to extend the application of these principles to the process of member-to-group generalization in stereotype change. As predicted, across the three studies (Ns = 60, 78, and 101), accountability was found to amplify generalization under control conditions, both when the member information was stereotypical (Experiment 1) and counterstereotypical (Experiments 2 and 3). Accountability was found to attenuate generalization (Experiments 2 and 3) when a meta-judgmental cue discredited the validity of the member information for the group judgment. Ancillary evidence from Experiments 2 and 3 suggests a mediational role for the cognitive fencing-off of the member information from the group schema. The implications of the observed interplay between stereotyping and meta-cognitions for theory and policy are discussed.
