Recognition: Recognizing The Brother And The Other: Avishai Margalit

Recognition is a name of a problem rooted in German idealism and Hegel's thought. It is not one problem but a family of problems. Indeed, it is a research programme, in which Axel Honneth is an important practitioner.
The tree of knowledge, like other trees, should be inspected by its fruits and not by exposing its roots. So my main concern is in rendering the problem of recognition in current idiom, rather than in Hegel's original idiom. What I shall try to do here is to present an account of the problem of recognition, which is parallel to the account suggested in Honneth's Struggle of Recognition . It is parallel in Plutarch's sense of 'parallel' lives, namely as an object of comparison.     

Numerical-spatial representation affects spatial coding: binding errors across the numerical distance effect

Does numerical-spatial representation affect feature binding? Studies of visual attention show that poor spatial coding leads to illusory conjunctions (ICs). In numerical cognition, it has been shown that numbers and space are not totally dissociated. This association underlies the numerical distance effect (DE): faster responses as the distance between the compared digits becomes larger (2 7 vs. 2 4). We used the DE to test whether numerical-spatial representation is available to visual processes that rely on spatial coding, such as feature binding. Participants reported the larger of two colored numbers. Both numerical distance (distances 2 and 5) and number–space congruity (e.g., congruent pair, 1 3; incongruent pair, 3 1) were analyzed. Results showed a higher proportion of ICs for distance 2 than for distance 5, providing strong evidence that numerical-spatial representation (1) entails a strong location code and (2) is available to visual processes that rely on location information.     

The numerical distance effect is task dependent

Number comparison tasks produce a distance effect e.g., Moyer & Landauer (Nature 215: 1519-1520, 1967). It has been suggested that this effect supports the existence of semantic mental representations of numbers. In a matching task, a distance effect also appears, which suggests that the effect has an automatic semantic component. Recently, Cohen (Psychonomic Bulletin & Review 16: 332-336, 2009) suggested that in both automatic and intentional tasks, the distance effect might reflect not a semantic number representation, but a physical similarity between digits. The present article (1) compares the distance effect in the automatic matching task with that in the intentional number comparison task and suggests that, in the latter, the distance effect does include an additional semantic component; and (2) indicates that the distance effect in the standard automatic matching task is questionable and that its appearance in previous matching tasks was based on the specific analysis and design that were applied.     

Reflexive orienting by central arrows: Evidence from the inattentional blindness task

It was demonstrated that central arrows produce orienting of attention even when they are nonpredictive as to the target location. This finding was suggested to indicate reflexive orienting of attention by central arrows. However, it is not clear whether central arrows can produce an attentional effect without awareness. In two experiments, using a variation of the inattentional blindness task, we examine whether orienting of attention by a central arrow can be demonstrated without conscious perception of the arrow. We found that attention could be directed to the cued location even when the arrow was not consciously perceived.     

Is it for real? Evaluating authenticity of musical pitch-space synesthesia

In spatial-sequence synesthesia, ordinal sequences are visualized in explicit spatial locations. We examined a recently documented subtype in which musical notes are represented in spatial configurations, to verify consistency and automaticity of musical pitch-space (M-S) synesthesia. An M-S synesthete performed a mapping pre-task (Exp. 1) used to indicate the locations of 7 auditory or visually presented notes, in 2 sessions a month apart. Results revealed strong correlations between sessions, suggesting the synesthete's musical forms were consistent over time. Experiment 2 assessed automaticity of M-S synesthesia. The same synesthete and matched controls preformed a spatial Stroop-like task. Participants were presented with an auditory or visual musical note and then had to reach for an asterisk (target) with a mouse cursor. The target appeared in a compatible or incompatible location (according to the synesthete's spatial representation). A compatibility effect was found for the synesthete but not for controls. The synesthete was significantly faster when the target appeared in compatible locations than in incompatible ones. Our findings show that for synesthetes, auditory and visually presented notes automatically trigger attention to specific spatial locations according to their specific M-S associations.     

A unique asymmetrical stroop effect in absolute pitch possessors

The Stroop task has been employed to study automaticity or failures of selective attention for many years. The effect is known to be asymmetrical, with words affecting color naming but not vice versa. In the current work two auditory-visual Stroop-like tasks were devised in order to study the automaticity of pitch processing in both absolute pitch (AP) possessors and musically trained controls without AP (nAP). In the tone naming task, participants were asked to name the auditory tone while ignoring a visual note name. In the note naming task, participants were asked to read a note name while ignoring the auditory tone. The nAP group showed a significant congruency effect only in the tone naming task, whereas AP possessors showed the reverse pattern, with a significant congruency effect only in the note reading task. Thus, AP possessors were unable to ignore the auditory tone when asked to read the note, but were unaffected by the verbal note name when asked to label the auditory tone. The results suggest that pitch identification in participants endowed with AP ability is automatic and impossible to suppress.     

The dependence of semantic relatedness effects upon prime processing

The semantic relationship between a prime and a target word has been shown to affect the speed at which the target word is processed. This series of experiments investigated how the semantic priming effect is influenced by the nature of the task performed on the prime word. Subjects were asked to perform either a naming or a letter-search task on the prime word and either a lexical-decision or color-naming task on the target word. When the primes were named, response times for the target words were facilitated in the lexical-decision task and inhibited in the color-naming task. However, these effects were eliminated or reduced to an insignificant level when the primes were searched for letters. We suggest that in order to produce the usual priming effect, the primes have to be processed for meaning rather than probed for constituents.
