Is Intentionality Dependent upon Consciousness?

It is often assumed thatconsciousness and intentionality are twomutually independent aspects of mental life.When the assumption is denounced, it usuallygives way to the claim that consciousness issomehow dependent upon intentionality. Thepossibility that intentionality may bedependent upon consciousness is rarelyentertained. Recently, however, John Searle andColin McGinn have argued for just suchdependence. In this paper, I reconstruct andevaluate their argumentation. I am in sympathyboth with their view and with the lines ofargument they employ in its defense. UnlikeSearle and McGinn, however, I am quite attachedto a naturalist approach to intentionality. Itwill turn out to be somewhat difficult toreconcile naturalism with the notion thatintentionality is dependent upon consciousness,although, perhaps surprisingly, I will arguethat McGinn's case for such dependence iscompatible with naturalism.     

Is binocular fusion of "cortical yellow" an illusion, contingent upon abstraction of coherent sensory information from the two eyes?

This research on the binocular fusion of phenomenal yellow, given red-filtered flashes of light in one eye and green-filtered flashes of light in the other, directly compared the effects of wider-bandwidth and narrow-bandwidth filtering. 20 male college students with normal stereopsis, Mage = 19.3 yr., SD = 2.2, were tested for the binocular perception of flashing yellow sensations given wider-bandwidth versus narrow-bandwidth filtering of light flashes which, monocularly, were experienced as red sensations in one eye and as green sensations in the other. When 3 wide-bandwidth tests for binocular yellow fusion were alternated with 3 narrow-bandwidth tests, simultaneous flashes of red-filtered light in one eye and green-filtered light in the other were binocularly perceived as yellowish on 25% of the wide-bandwidth tests (SD = 40%)--as yellow on 8% of the tests, orange on 12% of the tests, yellow-green on 5% of the tests-and were binocularly perceived as yellowish on 0% of the narrow-bandwidth tests. When wider-bandwidth and narrow-bandwidth testing were separated spatially and conducted contemporaneously, the red-filtered flashes in one eye and green-filtered flashes in the other were binocularly experienced as yellowish sensations by 80% of all participants under wider-bandwidth conditions--as yellow by 55%, orange by 10%, yellow-green by 15%--and as yellowish sensations by 0% of the participants under narrow-bandwidth conditions.     

Is developing scientific thinking all about learning to control variables?

Academically low-performing urban sixth graders engaged in inquiry activity received a suggestion that they focus their investigation on the role of a single factor. This suggestion had significant effects on their use of a superficially dissimilar strategy--controlling the variation of other factors. This latter strategy has received the lion's share of attention in research on the development of scientific reasoning. These results have implications, we propose, for what undergoes development with respect to scientific thinking and how this development can best be facilitated.     

Prejudice and peace: Is the Swedish youth neutral in its attitudes?

Two hundred and sixty Swedish students attending grade 9 were given a semantic differential to measure their attitudes towards four countries, Sweden, West Germany, USA, and the Soviet Union. The Soviet Union received significantly more unfavourable ratings on nearly all variables than the other countries, which received mainly favourable or neutral ones. Most interesting, the Soviet Union is rated as "enemy", whilst the other countries are rated as "friends". Implications for peace education are discussed.     

Attentional effects of negative faces: Top-down contingent or involuntary?

Recent research has substantiated that schematic negative faces are found more efficiently than positive faces among crowds of distractor faces of varying set sizes. The present study asks whether this relative search asymmetry (RSA) is intention driven or due to involuntary attentional capture. To that aim, participants were first tested in a condition in which negative and positive faces were searched for, and then in a condition in which negative or positive schematic faces appeared at chance level at the position of the target (valid trials) or of a distractor (invalid trials), the faces thus being task irrelevant (the 1/n paradigm). The expected search benefit for valid negative-face target trials most clearly occurred when participants searched for a target defined by a conjunction of color and position; when the target was defined either by an orientation or color singleton, we found rather weak or no evidence for involuntary attention capture by negative faces. We see the results as being (1) evidence that the RSA is partly based on stimulus-driven factors that occur independently of the intention to search for a positive or negative face, and (2) consistent with the assumption that the effects are mainly due to a more efficient rejection of positive-face than of negative-face distractors, rather than being due to attentional capture by the target     

Breaking down unitization: Is the whole greater than the sum of its parts?

Memory impairments are often observed in aging. Specifically, older adults have difficulty binding together disparate elements (relational memory). We have recently shown that a cognitive strategy known as unitization can mitigate impaired relational learning in the transverse patterning task (TP) in both amnesia and healthy aging. This strategy allows items to be fused together through an interaction such that one item acts upon another. In the context of TP, unitization is comprised of three component processes: (1) fusion, (2) motion, and (3) semantic comprehension of action/consequence sequences. Here, we examine which of these components are sufficient to mitigate age-related impairments. Four groups of older adults were given either the full unitization strategy or one of the three component strategies. Each group of older adults showed impairments in memory for the relations among items under standard training instructions relative to a threshold that marks learning of a winner-take-all rule (elemental threshold). However, participants who were given either the full unitization strategy or the action/consequence-only strategy showed improved performance, which was maintained following the 1-hour delay. Therefore, semantically rich action/consequence interactions are sufficient to mitigate age-related relational memory impairments.     

Students' ratings of teaching effectiveness: a laughing matter?

Gump in 2004 identified a positive significant relationship between awareness of daily class objectives and ratings of the instructor's overall teaching effectiveness. The idea that rating of teaching effectiveness can be related to other non-teaching related attributes of the lecturer was further examined. Correlations based on ratings of teaching effectiveness from 453 undergraduate students (M=21 yr., SD= 5.5; 73% women) showed that another nonteaching related variable, namely, how funny the instructor was perceived, was significantly related to indicators of teaching effectiveness.     

Family therapy research: What are the most important variables?

This report summarizes the results of a nearly day-long session of a group of experienced and distinguished family therapy practitioners and researchers. The task the group set for itself was to begin delineating the most important variables to attend to in understanding family therapy and evaluating its effectiveness. With full recognition that such a task could be only partially and tentatively accomplished in the time allotted, a great many such variables were outlined.     

Is `Property' Necessary? On Owning the Human Body and its Parts

Courts usually treat control over human bodies and body parts as a property issue and find that people do not have property rights in themselves. This contradicts the liberal philosophical principle that people should be able to perform any self-regarding actions that do not cause harm to others. The philosophical inconsistencies under pinning the legal treatment of body parts arguably stem from a misplaced judicial preoccupation with‘property’. A better approach would be to hold a policy inquiry into the degree of liberty a society wishes to grant its inhabitants. Only once this substantive issue has been addressed should property be raised as a possible method of implementing the policy. This revised version was published online in August 2006 with corrections to the Cover Date.     

Is flanker-based inhibition related to age? Identifying specific influences of individual differences on neurocognitive variables

Researchers frequently attempt to identify the specific neurocognitive processes that might be responsible for differences in performance associated with neurological status or other individual difference characteristics by administering two or more conditions of an experimental task to different groups of participants, and focusing on the group-by-condition interaction as the primary outcome of interest. Three limitations of this approach are discussed, and an alternative analytical method is proposed to overcome the limitations. The method is demonstrated in analyses of data from 10 cognitive tasks in two independent studies, including two flanker tasks which are often used to assess aspects of inhibition.     

Magnitude comparison in preschoolers: what counts? Influence of perceptual variables

This study examined numerosity comparison in 3-year-old children. Predictions derived from the analog numerical model and the object-file model were contrasted by testing the effects of size and ratio between numerosities to be compared. Different perceptual controls were also introduced to evaluate the hypothesis that comparison by preschoolers is based on correlated perceptual variables rather than on number per se. Finally, the relation between comparison performance and verbal counting knowledge was investigated. Results showed no evidence that preschoolers use an analog number magnitude or an object-file mechanism to compare numerosities. Rather, their inability to compare sets controlled for surface area suggests that they rely on perceptual cues. Furthermore, the development of numerosity-based representations seems to be related to some understanding of the cardinality concept.     

Global Justice: Is Interventionalism Desirable?

In 1994, the European Parliament published a resolution on the right of humanitarian intervention. Interestingly, the declaration maintains that such intervention is not in contradiction with international law, although it formulates the concept of right in a way that is translatable into the vocabulary of individual rights. I analyze some implications of the resolution for the mutual duties of states. I thereby focus my attention on two possible applications: by way of Rawls's duty of assistance and by way of the cosmopolitan theory of global distributive justice. I conclude that the latter theory promises better results for protecting individuals' basic rights, but I also show that it is at the cost of a strongly interventionist structure requiring a powerful supranational institution. Finally, I envision the conditions under which such an increase of interventionism in favor of human rights can be acceptable.     

Sexual Morality: Is Consent Enough?

The liberal view that valid consent is sufficient for a sex act to be morally legitimate is challenged by three major philosophies of sex: the Catholic view of sex as ordained for procreation and properly confined to marriage, the romantic view of sex as bound up with love, and the radical feminist analysis of sex in our society as part and parcel of the domination of women by men. I take a critical look at all three, focusing on Mary Geach's recent statement of the procreation view, Roger Scruton's theory of sexual desire as naturally evolving into intimacy and love, and several radical feminist discussions of sex in sexist society which argue that the notion of consent is unhelpful and, indeed, irrelevant. I argue that none of these lines of argument is convincing, and that consent remains the touchstone of morally permissible sex – although, dmittedly, it may not be very helpful in discussing ideals of human sexuality.
