Cascade models of word production assume that during lexical access all activated concepts activate their names. In line with this view, it has been shown that naming an object's colour is facilitated when colour name and object name are phonologically related (e.g., "blue" and "blouse"). Prevor and Diamond's (2005) recent observation that…

There is now a large body of evidence suggesting that color and photographic detail exert an effect on recognition of visually presented familiar objects. However, an unresolved issue is whether these factors act at the visual, the semantic or lexical level of the recognition process. In the present study, we investigated this issue by having…

In many nonhuman species of vertebrates, females are attracted to red on male conspecifics. Red is also a signal of male status in many nonhuman vertebrate species, and females show a mating preference for high-status males. These red-attraction and red-status links have been found even when red is displayed on males artificially. In the present…

In this article, the author describes the design for her advanced oil-painting class. In this class, high-school students created a self-portrait painting and learned a glazing technique. The author also describes the students' evaluation of the class.

This study investigated the visual information that children and adults consider while switching or maintaining object-matching rules. Eye movements of 5- and 6-year-old children and adults were collected with two versions of the Advanced Dimensional Change Card Sort, which requires switching between shape- and color-matching rules. In addition to…

The aim of this study was to make visible, and understand, possible opportunities for school improvement based on schoolchildren's lived experience and visionary ideas of school. Schoolchildren aged 10-12 from the northern part of Sweden participated in the study. The phenomenological analysis resulted in three themes, with no particular order of…

A new family of removable colored coatings that could make temporary messages is developed by employing alginates. The nontoxic, biodegradable coating is made by using calcium alginate and dyes that are widely used as food colorants and adheres easily and firmly to surfaces and could be removed by treating with a non-toxic solution of ethylene…

After studying the endangered species prints of Andy Warhol, and viewing several interviews with the artist, fifth-grade students were still hungry for more information about this eccentric artist, who tested every rule and broke most of them. In this article, the author describes a project using silkscreen to help students truly understand how…

Categorical perception (CP) is said to occur when a continuum of equally spaced physical changes is perceived as unequally spaced as a function of category membership (Harnad, S. (Ed.) (1987). Psychophysical and cognitive aspects of categorical perception: A critical overview. Cambridge: Cambridge University Press). A common suggestion is that CP…

The view that Attention Deficit/Hyperactivity Disorder (ADHD) is associated with a diminished ability to control interference is controversial and based exclusively on results of (verbal)-visual interference tasks, primarily the Stroop Color Word task. The present study compares medication-naive children with ADHD (n = 35 and n = 51 in Experiments…

A handheld digital microscope (HDM) interfaced to a computer with a presentation projector is used to project an out-of-focus yellow patch on the screen, then the patch is brought into focus to show that, paradoxically, there are red and green but no yellow pixels. Chromaticity diagrams are used to discuss this observation and spectroscopic…

Patients with semantic dementia show a specific pattern of impairment on both verbal and non-verbal "pre-semantic" tasks, e.g., reading aloud, past tense generation, spelling to dictation, lexical decision, object decision, colour decision and delayed picture copying. All seven tasks are characterised by poorer performance for items that are…

Recent research has demonstrated that adults successfully segment two interleaved artificial speech streams with incongruent statistics (i.e., streams whose combined statistics are noisier than the encapsulated statistics) only when provided with an indexical cue of speaker voice. In a series of five experiments, our study explores whether…

Purpose: Communication about feelings is a core element of human interaction. Aided augmentative and alternative communication systems must therefore include symbols representing these concepts. The symbols must be readily distinguishable in order for users to communicate effectively. However, emotions are represented within most systems by…

In this article, the author describes a self-portrait project she developed for her students. The project emphasizes personality and pattern as the main objectives through a series of steps that include drawing exercises, observation skills, stream-of-color, intense patterning and texturizing, and colored pencil techniques. By drawing down the…
