Beyond perception: Testing for implicit conceptual traces in high-load tasks

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. (2009). Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks. Consciousness and Cognition, 18, 811–819.] study and discusses them in relation to the Perceptual Load Theory of Lavie [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings.     

Both exogenous and endogenous target salience manipulations support resource depletion accounts of the attentional blink: A reply to Olivers, Spalek, Kawahara, and Di Lollo (2009)

Input control theories of the attentional blink (AB) suggest that this deficit results from impaired attentional selection caused by the post-Target 1 (T1) distractor (Di Lollo, Kawahara, Ghorashi, & Enns, 2005; Olivers, van der Stigchel, & Hulleman, 2007). Accordingly, these theories predict that there should be no AB when no distractors intervene between the targets. Contrary to these hypotheses, Dux, Asplund, and Marois (2008) observed an AB (T3 deficit) when three targets, from the same attentional set, were presented successively in a rapid stream of distractors, if subjects increased the resources they devoted to T1 processing. This result is consistent with resource depletion accounts of the AB. However, Olivers, Spalek, Kawahara, and Di Lollo (2009) argue that Dux et al.’s results can be better explained by the relationship between T1 and T2, and by target discriminability effects, rather than by the relationship between T1 and T3. Here, we find that manipulating the resources subjects devote to T1, either exogenously (target perceptual salience) or endogenously (target task relevance), affects T3 performance, even when T2 and target discriminability differences are controlled for. These results support Dux et al.’s conclusion that T1 resource depletion underlies the AB.     

Early morphological processing is morphosemantic and not simply morpho-orthographic: A violation of form-then-meaning accounts of word recognition

Many studies have suggested that a word’s orthographic form must be processed before its meaning becomes available. Some interpret the (null) finding of equal facilitation after semantically transparent and opaque morphologically related primes in early stages of morphological processing as consistent with this view. Recent literature suggests that morphological facilitation tends to be greater after transparent than after opaque primes, however. To determine whether the degree of semantic transparency influences parsing into a stem and a suffix (morphological decomposition) in the forward masked priming variant of the lexical decision paradigm, we compared patterns of facilitation between semantically transparent (e.g., coolant—cool) and opaque (e.g., rampant—ramp) prime—target pairs. Form properties of the stem (frequency, neighborhood size, and prime—target letter overlap), as well as related—unrelated and transparent—opaque affixes, were matched. Morphological facilitation was significantly greater for semantically transparent pairs than for opaque pairs. Ratings of prime—target relatedness predicted the magnitude of facilitation. The results limit the scope of form-then-meaning models of word recognition and demonstrate that semantic similarity can influence even early stages of morphological processing.

Beyond the Conflict: Religion in the Public Sphere and Deliberative Democracy

Traditionally, liberals have confined religion to the sphere of the ‘private’ or ‘non-political’. However, recent debates over the place of religious symbols in public spaces, state financing of faith schools, and tax relief for religious organisations suggest that this distinction is not particularly useful in easing the tension between liberal commitments to equality on the one hand, and freedom of religion on the other. This article deals with one aspect of this debate, which concerns whether members of religious communities should receive exemptions from regulations that place a distinctively heavy burden on them. Drawing on Habermas’ understanding of churches as ‘communities of interpretation’, we explore possible alternatives to both the ‘rule-and-exemption’ approach and the ‘neutralist’ approach. Our proposal rests on the idea of mutual learning between secular and religious perspectives. On this interpretation, what is required is (i) the generation and maintenance of public spaces in which there could be discussion and dialogue about particular cases, and (ii) evaluation of whether the basic conditions of moral discourse are present in these spaces. Thus deliberation becomes a touchstone for the building of a shared democratic ethos.     

Dynamics of Flow: A Nonlinear Perspective

The aims of this study are to consider the experience of flow from a nonlinear dynamics perspective. The processes and temporal nature of intrinsic motivation and flow, would suggest that flow experiences fluctuate over time in a dynamical fashion. Thus it can be argued that the potential for chaos is strong. The sample was composed of 20 employees (both full and part time) recruited from a number of different organizations and work backgrounds. The Experience Sampling Method (ESM) was used for data collection. Once obtained the temporal series, they were subjected to various analyses proper to the complexity theory (Visual Recurrence Analysis and Surrogate Data Analysis). Results showed that in 80% of the cases, flow presented a chaotic dynamic, in that, flow experiences delineated a complex dynamic whose patterns of change were not easy to predict. Implications of the study, its limitations and future research are discussed.     

Becoming human,becoming sober

Two themes run through Kierkegaard’s authorship. The first defines existential requirements for “becoming human”—reflective honesty and earnest humor. The second demarcates the religious phenomena of sobriety when human becoming suffers insurmountable collisions. Living with existential pathos teaches the difference between the either/or logic of collisions and the both/and logic of development and transitions. There is a difference between self-transformation and a progressive individual and social development. In the developmental mode self experiences gradual progression or adaptive evolution; in the self-transformative mode self undergoes qualitative upsurges, leaps, gestalt switches, musical key transpositions of becoming in individual and social evolutions. Each individual in every epoch begins at the beginning. The author traces the movements of becoming in their parallel dimensions, drawing a fork through Kierkegaard’s writing. The first leads through the existence spheres of his pseudonymous authorship. The second intensifies the movement on the spot and in the moment.

A standardized set of 260 pictures for Modern Greek: Norms for name agreement, age of acquisition, and visual complexity

The appropriate selection of both pictorial and linguistic experimental stimuli requires a previous languagespecific standardization process of the materials across different variables. Considering that such normative data have not yet been collected for Modern Greek, in this study normative data for the color version of the Snodgrass and Vanderwart picture set (Rossion & Pourtois, 2004) were collected from 330 native Greek adults. Participants named the pictures (providing name agreement ratings) and rated them for visual complexity and age of acquisition. The obtained measures represent a useful tool for further research on Greek language processing and constitute the first picture normative study for this language. The picture norms from this study and previous ones may be downloaded from brm.psychonomic-journals.org/content/supplemental.
