On Bound Variable Interpretations: The LF-Only Hypothesis

Under what conditions do perceivers prefer to assign a bound variable interpretation to a pronominal that is ambiguous between a bound variable and a coreferential interpretation? Several experiments were designed to test the hypothesis that language perceivers prefer a bound variable over a coreferential interpretation of a pronoun because the former only requires consultation of a logical form (LF) representation, while the latter requires access to a discourse representation. The hypothesis was disconfirmed in two respects. First, although bound variable interpretations show a processing advantage over coreferential interpretations in VP ellipsis constructions, the preference for bound variable interpretations is not general--it does not extend to other quantificational contexts. Second, the preference for bound variable interpretations in VP ellipsis constructions is not limited to examples in which the antecedent and the ellipsis site occur in the same sentence. If the bound variable advantage were due to the ready availability of the LF for the current sentence, the advantage should disappear across sentence boundaries. An alternative hypothesis is then considered which could explain the source of the bound variable advantage in VP ellipsis contexts.     

The importance of being expert: Top-down attentional control in visual search with photographs

Two observers looking at the same picture may not see the same thing. To avoid sensory overload, visual information is actively selected for further processing by bottom-up processes, originating within the visual image, and top-down processes, reflecting the motivation and past experiences of the observer. The latter processes could grant categories of significance to the observer a permanent attentional advantage. Nevertheless, evidence for a generalized top-down advantage for specific categories has been limited. In this study, bird and car experts searched for face, car, or bird photographs in a heterogeneous display of photographs of real objects. Bottom-up influences were ruled out by presenting both groups of experts with identical displays. Faces and targets of expertise had a clear advantage over novice targets, indicating a permanent top-down preference for favored categories. A novel type of analysis of reaction times over the visual field suggests that the advantage for expert objects is achieved by broader detection windows, allowing observers to scan greater parts of the visual field for the presence of favored targets during each fixation.     

A comparison of upper vs. lower and right vs. left visual fields using lexical decision

A series of experiments using the lexical decision task was conducted in order to investigate the functional differences between the upper and lower visual fields (UVF, LoVF) in word recognition. Word-nonword discrimination was swifter and more accurate for word stimuli presented in the UVF. Changing the eccentricity did not affect the UVF advantage over the LoVF. UVF superiority over LoVF was found to be equivalent for both right and left visual hemifield (RVF, LVF). In general, presenting related word primes enhanced all visual field differences in a similar manner (UVF over LoVF and RVF over LVF). However, primes consisting of semantically constraining sentences enhanced the RVF advantage over the LVF, but did not affect the UVF and LoVF differentially. The argument is made that UVF superiority cannot be due to perceptual or attentional differences alone, but must also reflect top-down information flow.     

The effect of vertical and horizontal symmetry on memory for tactile patterns in late blind individuals

Visual stimuli that exhibit vertical symmetry are easier to remember than stimuli symmetric along other axes, an advantage that extends to the haptic modality as well. Critically, the vertical symmetry memory advantage has not been found in early blind individuals, despite their overall superior memory, as compared with sighted individuals, and the presence of an overall advantage for identifying symmetric over asymmetric patterns. The absence of the vertical axis memory advantage in the early blind may depend on their total lack of visual experience or on the effect of prolonged visual deprivation. To disentangle this issue, in this study, we measured the ability of late blind individuals to remember tactile spatial patterns that were either vertically or horizontally symmetric or asymmetric. Late blind participants showed better memory performance for symmetric patterns. An additional advantage for the vertical axis of symmetry over the horizontal one was reported, but only for patterns presented in the frontal plane. In the horizontal plane, no difference was observed between vertical and horizontal symmetric patterns, due to the latter being recalled particularly well. These results are discussed in terms of the influence of the spatial reference frame adopted during exploration. Overall, our data suggest that prior visual experience is sufficient to drive the vertical symmetry memory advantage, at least when an external reference frame based on geocentric cues (i.e., gravity) is adopted.     

A positive patterning advantage with complex but not simple patterning: A cue constellation approach

Determinants of a positive patterning advantage (that is, an advantage for positive patterning over negative patterning) in human causal reasoning were examined in an experiment that compared simple patterning discriminations (A, B vs. AB) to complex patterning discriminations (AB, BC, AC vs. ABC). As predicted by a cue constellation analysis of complex discriminations, a positive patterning advantage was found with complex patterning but not with simple patterning discriminations. This result may explain why some recent studies have found a positive patterning advantage where earlier studies had failed to find one. The interaction of patterning complexity with the positive patterning advantage appears to pose problems for rule-based accounts of patterning. The results support the view that associative theories of human causal reasoning are more easily distinguished from rule-based approaches when applied to conditions that make simple rules difficult to identify or implement.     

Cultural Effects Rather Than a Bilingual Advantage in Cognition: A Review and an Empirical Study

The bilingual advantage hypothesis contends that the management of two languages in the brain is carried out through domain‐general mechanisms, and that bilinguals possess a performance advantage over monolinguals on (nonlinguistic) tasks that tap these processes. Presently, there is evidence both for and against such an advantage. Interestingly, the evidence in favor has been thought strongest in children and older adults, leading some researchers to argue that young adults might be at peak performance levels, and therefore bilingualism is unable to confer an improvement. We conducted a large‐scale review of the extant literature and found that the weight of research pointed to an absence of positive evidence for a bilingual advantage at any age. We next gave a large number of young adult participants a task designed to test the bilingual advantage hypothesis. Reasoning from the literature that young adults from an East Asian (Korean) culture would likely outperform those from a Western (British) culture, we also compared participants on this factor. We found no evidence for a bilingual advantage but did find evidence for enhanced performance in the Korean group. We interpret these results as further evidence against the bilingual advantage hypotheses.     

Comparison of the home advantage in nine different professional team sports in Spain

Home advantage is a well-established phenomenon in many sports. The present study is unique in that it includes different sports analysed in the same country, at the same level of competition, and over the same time period. Nine team sports from Spain were included: baseball, basketball, handball, indoor soccer, roller hockey, rugby, soccer, volleyball, and water polo. Data for five seasons (2005-2006 to 2009-2010) were obtained, totaling 9,472 games. The results confirmed the existence of home advantage in all nine sports. There was a statistically significant difference between the sports; home advantage was highest in rugby (67.0%), and lowest in volleyball (55.7%), water polo (56.2%), and roller hockey (58.3%). The design of the study controlled for some of the likely causes of home advantage, and the results suggested that the high home advantage for rugby was likely a reflection of the continuous, aggressive, and intense nature of the sport.     

Computational and reasoning abilities in arithmetic: Cross-generational change in China and the United States

A Chinese advantage over Americans was found for economically relevant computational and reasoning abilities in arithmetic for groups of 6th- and 12th-grade students matched or equated on general intelligence. No cross-national difference for computational or reasoning abilities was found for samples of older (60- to 80-year-old) Chinese and American adults equated on general intelligence. The pattern of change in arithmetical competencies across cohorts suggests that the Chinese advantage in 6th and 12th grade is due to a cross-generational decline in competencies in the United States and a cross-generational improvement in China.     

Asymmetries in perception of tachistoscopically presented horizontal and vertical random-letter strings

Two studies examined perception of briefly presented (100-msec.) strings of letters. In Study One, 20 subjects were presented horizontal 5-letter strings in the left, central, and right visual fields. These were compared with 5-letter vertical strings presented centrally in the lower, central, and upper visual fields. Similar within-string patterns were found for all presentations. Between strings there was a typical right over left visual-field advantage in accuracy of report for horizontal strings. There was no equivalent lower over upper visual-field advantage for vertical strings. In Study Two, 24 subjects were presented vertical strings in the right and left visual fields, vertical strings in the upper and lower visual fields, and horizontal strings in the right and left visual fields. A post-stimulus cueing technique for single letters was used. Between-strings, the same right over left visual-field advantage for horizontal strings was noted but not for vertical strings. Between strings no advantage for lower over upper visual fields was found. An interaction for within-string patterns and visual field was found for vertical strings presented in the upper and lower visual fields. These results are explained in terms of an interaction between scanning and masking effects depending upon orientation and visual field.     

Problem-oriented training promotes spontaneous analogical transfer: Memory-oriented training promotes memory for training

Spontaneous analogical transfer is the use of information from one problem to solve another problem, without an explicit hint to use the previous information. The results of five experiments were that if subjects tried to solve a training problem before hearing its solution, or tried to explain a training story's solution before hearing the correct explanation, spontaneous transfer was more likely than it was if subjects had studied the same training passage for memory before hearing its solution or explanation. The advantage of problem-oriented processing over memory-oriented processing occurred even though solution attempts nearly always failed, and the advantage was not reduced if the target problem was tested 15 min later rather than immediately after training. We propose that problem-oriented processes performed at study are appropriate processes to use at test. Further support for the account comes from subjects' memory for the training passages; the advantage for problem-oriented processing on solution tasks was mirrored by an equally substantial advantage for the memory-oriented subjects on a recall task.     

Conceptualism and the New Myth of the Given

The motivation for McDowell’s conceptualism is an epistemological consideration. McDowell believes conceptualism would guarantee experience a justificatory role in our belief system and we can then avoid the Myth of the Given without falling into coherentism. Conceptualism thus claims an epistemological advantage over nonconceptualism. The epistemological advantage of conceptualism is not to be denied. But both Sellars and McDowell insist experience is not belief. This makes it impossible for experience to justify empirical knowledge, for the simple reason that what is not a belief cannot justify a belief. Nondoxastic experience, though conceptual, is still a Given. And what conceptualism gives us can only be a New Myth of the Given.     

Privileged access to action for objects relative to words

We compared action (pour or twist?) and contextual/semantic (found in kitchen?) decisions made to pictures of objects, nonobjects, and words. Although there was no advantage for objects over words in contextual/semantic decisions, there was an advantage for objects over words and nonobjects in action decisions. For objects, both action and contextual/semantic decisions were faster than naming; for words, the opposite occurred. These results extend the early results of Potter and Faulconer (1975) that there is privileged access to semantic memory for objects relative to that for words and privileged access to phonology for words. Our data suggest that, for objects, there is privileged access to action knowledge rather than to all forms of semantic knowledge and that this is contingent on learned associations between objects and actions.     

The status of consonants and vowels in phonological assembly: Testing the two-cycles model with Italian

Recent studies by Berent and Perfetti (1995) and Lee, Rayner, and Pollatsek (2001) have shown a processing priority of consonants over vowels in tasks like backward masking and reading, respectively. One possible explanation for this advantage of consonants is in terms of the specific characteristics of the English spelling (i.e., a great inconsistency in the spelling-sound relations for vowels), and therefore is not predicted for a language, like Italian, with a transparent orthography. The aim of the present experiments was to investigate the consonant advantage in Italian with the backward masking paradigm. The first two experiments, with a perceptual identification and a naming task, showed a masking reduction effect for masks sharing vowels with the target at the shortest SOAs, in addition to a pseudo-homophone advantage as compared to the control condition. In the third experiment, where a lexical decision task was used, the advantage of the mask sharing vowels disappeared. The fourth experiment was a replication of Experiment 1 with different materials. Overall, the results suggest that the advantage of consonants can only be found in English, whereas in Italian, for which the computation of phonology of vowels and consonants is similar, no effect is apparent. Thus, the processing priority for consonants seems to depend on the inconsistencies of vowel phonology in English.     

Right-hemispheric dominance for processing extended non-linguistic frequency transitions

The left hemisphere is specialized for most linguistic tasks and the right hemisphere is specialized for many non-linguistic tasks, but the cause of these functional asymmetries is unknown. One of the stimulus factors that appears to influence these asymmetries is the rate at which stimuli change. In the present experiment, 41 participants completed the Fused Dichotic Words Test (FDWT) and a non-linguistic Frequency Transition Task (FTT) wherein the Frequency Transitions (FTs) were either rapid (40 ms) or relatively slow (200 ms). There was a right hemisphere advantage for slow FTs when the change was at the front of the stimulus, but no corresponding left hemisphere advantage for the rapid FTs. There was no relationship between either FTT and the left hemisphere advantage exhibited on the FDWT. This finding provides support for the position that the right hemisphere dominates tasks that require temporal processing over relatively long periods of time.     

Does survival context enhance memory for source? A within-subjects comparison

ABSTRACT

Nairne, Thompson, and Pandeirada [2007. Adaptive memory: Survival processing enhances retention. Journal of Experimental Psychology: Learning, Memory, and Cognition, 33, 263–273] demonstrated that processing words according to their relevance to a survival scenario enhanced their subsequent retrieval in recall and recognition tasks compared to a variety of control scenarios. From an adaptive perspective, it is maintained that processing words in a survival context should also enhance memory for source; however, evidence in the literature is rather mixed regarding a survival context advantage for source memory. In the current study, we conducted four experiments to systematically investigate the survival advantage in source memory, when the context itself is the source, with both recall (Experiments 1A and 1B) and recognition tests (Experiments 2A and 2B). Results showed a survival advantage for item memory over the control contexts in all experiments. The survival context advantage was not extended to source memory performance in Experiment 1A. Results from all other experiments, however, indicated a survival context advantage for both item and source memory. Findings are discussed in relation to possible proximate mechanisms underlying the survival processing effect.     

Preparatory processes in the task-switching paradigm: evidence from the use of probability cues

The purpose of the investigations was to dissociate processes of task preparation from task execution in the task-switching paradigm. The basic assumption was that task repetitions have 2 advantages over task shifts: an activation advantage as a result of the execution of the same task type in the pretrial, and an expectation advantage, because participants, in general, implicitly expect a repetition. In Experiments 1-3, the authors explicitly manipulated expectancies by presenting cues that announced a shift and/or a repetition with probabilities of 1.00, .75, .50, or .25. Increasing latencies with decreasing probability for shifts and repetitions show that the expectation advantage can be equalized by preparation. However, the activation advantage represented by constant shift costs between tasks of the same probability is not penetrable by preparation. In Experiments 4 and 5, the authors found evidence that preparation involves activation of the expected task and inhibition of distracting tasks.
