Prospective and retrospective time-keeping
As my mental/interval time-keeping knowledge development curve continues it's slow growth, it has become clear that one needs to become cognizant of the contemporary terminology in the psychology of time perception. One frequent distinction I run across when skimming research articles is the difference between retrospective and prospective time-keeping.
According to Wearden (2005):

According to Wearden (2005):
- A distinction central to modern time Psychology is that between prospective and retrospective timing, although the distinction was introduced only fairly recently in the long history of time perception by Hicks, Miller, and Kinsbourne (1976). Prospective timing involves time judgments made when experimental participants are alerted in advance that duration is an important feature of the procedure. Most common laboratory tasks are of this type (e.g. “hold down this button for one second,” “I’m going to present two tones and I want you to tell me which lasted longer”). In contrast, retrospective timing involves a time judgment made when the participant is unaware that a question about time is going to be asked (e.g. “how long is it since you started reading this paragraph?”). Contemporary time researchers are (virtually) unanimous that confusing these two is fatal to any proper progress (although they were routinely mixed up until recently, see the work reviewed in Fraisse (1964) for example), and that they are explained by different psychological mechanisms.

Music training and sensitivity to speech sounds (Ga)
Clearly the extant research literature has linked mental/interval time keeping and musical abilities (click here for some prior posts).
Nature Neuroscience has a new article that links musical training and sensitivity to speech sounds (Ga), an ability important for early reading. Check out this new post at IQ's Corner.

My Stroke Insight book

Thanks to Neurofuture for the tip re: a book (My Stroke Insight) that captures the personal journey of a neuroanatomist with suffered an AVM stroke, and how she regained many capabilities via innovative and traditional rehab methods. The following description was lifted from the link above:
Jill Taylor was a 37-year-old Harvard-trained brain scientist when a blood vessel exploded in her brain. Through the eyes of a curious scientist, she watched her mind deteriorate whereby she could not walk, talk, read, write, or recall any of her life. Because of her understanding of the brain, her respect for the cells in her body, and an amazing mother, Jill completely recovered. In My Stroke of Insight, she shares her recommendations for recovery and the insight she gained into the unique functions of the two halves of her brain. When she lost the skills of her left brain, her consciousness shifted away from normal reality where she felt "at one with the universe." Taylor helps others not only rebuild their brains from trauma, but helps those of us with normal brains better understand how we can consciously influence the neural circuitry underlying what we think, how we feel and how we react to life’s circumstances.

Mental time keeping scholar - Dr. Buonomano

In a prior post I announced the IQ Brain Clock blog "Mental Timing Scholars" link section (see side panel of this blog). Today I added a fifth researcher to this scholar honor role. This post is to highlight Dr. Dean Buonomano's research.
Below is a brief listing of his mental timing/temporal processing research interests (lifted from his lab web page). Although difficult for me to read (I'm still reading and rereading it), I've found his recent article with Dr. Karmarkar (Timing in the Absence of Clocks: Encoding Time in Neural Network States) particularly interesting since it suggests an alternative to the dominant internal mental clock theoretical/conceptual explanation for mental timing (a link to the article is provided in "key research articles" section of this blog).
NEURAL BASIS OF TEMPORAL PROCESSING
- Sensory stimuli, such as speech, are rich in temporal information on the time scale of tens to hundreds of milliseconds. The primary goal of my laboratory is to understand the neural basis of temporal information processing. Specifically, how do neurons develop selective responses to temporal characteristics such as the order, duration and intervals of different stimulus features' To answer this question the main approaches in my laboratory involve: (1) studying how cortical neural networks respond to temporal stimuli; (2) the characterization of time-dependent neuronal properties, and (3) studying short- and long-term synaptic plasticity. In parallel with these studies my laboratory also relies on computer simulations of artificial neural networks, and behavioral experiments aimed at characterizing temporal processing. Together these different approaches will be used to attempt to generate a theory of how the nervous system recognizes and categorizes complex sensory stimuli.

Mental timing and rhythm perception bibliography posted
As promised, I just posted the "working" mental/interval timing and rhythm perception reference list (click here) I've been pulling together the past week or so. It currently includes 340+ references. I've NOT read all of them, so I can't vouch that every reference is relevant to the focus of this blog. I hope to read some of the more important/seminal pieces as make blog posts as time permits.
If anyone finds this resource of value, let me know via a comment. Also, if you are aware of important references that are missing, drop me a comment or email note (iap@earthlink.net).

IQ brain clock suggested readings (3 books)

Sorry for the paucity of recent posts to this blog. I'm one not to make excuses, but (this time I will...it is my blog and I'm the blog dictator) since my auto accident in December, I've been having a hard time gaining traction on both my personal and professional life due to a combo of pleasant (I got engaged to the most wonderful lady in the world...my lady Di), unpleasant (a severe case of the winter crud...cold, hacking cough, etc.; need for PT from accident) and regular (work projects) events.
I've also been buried in efforts to put together a large/comprehensive reference list of contemporary scholarly publications dealing with mental/interval time-keeping and rhythm perception. It now stands at 300+ references. When it is done, I will post it to this blog.
In the process of putting together this reference list I've come across three books (see above) that may interest readers. Also, if anyone is looking to send the blogmaster a gift, any one (or all three) of these books would be nice :)
More information regarding these books can be found by clicking here, here, and here. As soon as I can (hopefully within the next 10 minutes) I will also add some kind of "recommended books" section to a side panel of this blog (that will include these books, and others I find as I trundle across the corpus of mental timing literature).

New timing blog - circadian emphasis
Bingo.
This afternoon I discovered another blog that covers topics related to the IQ Brain Clock blog (the blog you are reading). The blog is called "A blog around the clock" with a specific focus on human timing at the level of circadian rhythms (see prior post for the placement of circadian rhythms in the hierarchy of scales of human time perception).
As soon as I'm done with this post I'll be adding this blog to the IQ Brain Clock blog roll. Keep on ticking.......

WSJ reviews brain fitness products
Another article in the Wall Street Journal re: a number of the more visible brain-based products in the brain-fitness movement. If I had the time and resources it would be nice to do the following with these products, as well as many others that are available (see Sharp Brains for more)1. Task analyze the cognitive/neuropsychological abilities that appear to be activated/treated with each product using a standard/accepted taxonomy of human cognitive abilities. In the domain of cognitive abilities I, of course, would analyze the products using the CHC taxonomy of cognitive abilities. Having a handful of independent experts in CHC theory complete this task analysis and then establish an "expert consensus" would be nice. Long story short----lets examine all of these products using the same cognitive taxonomic model and terminology.
2. Conduct a study (or series of studies) where the effectiveness of the programs (at least 3-4) are compared head-to-head with either (a) the same subjects (of course, using a counter-balanced design) and/or (b) randomly assign subjects to different product treatment groups (or use some matched subject groups). The use of a control (non-treatment group) would also be ideal. Have all subjects take a standard battery of pre- and post-test cognitive/neuropsychological measures and statistically compare the relative treatment effects against the control group.
I'm sure there is more, but this would provide some useful information for the consumer in this whole brain fitness movement.
Finally, if any readers of this blog have had experience with any of these products, and/or are aware of published empirical effectiveness studies, please leave a comment.

More on UCLA mental time keeping theory
More press coverage (Scientific American.com) (see post the other day) highlighting the new UCLA research suggesting an alternative to the traditional pacemaker-accumulator model of mental or interval time-keeping in the brain.
According to Warren Meck, one of the prominent mental time researchers previously featured at this blog:

According to Warren Meck, one of the prominent mental time researchers previously featured at this blog:
- "This paper has important implications for our every day perception of the temporal relationships among all of the sights and sounds that we process." He adds that the study complements his research focusing on internal clock mechanisms—which he has localized to the basal ganglia at the brain's center—at durations of seconds to hours involving cognitive and memory processes.

UCLA alternative brain clock model proposed

Thanks to Omni Brain for the post regarding new research at UCLA that suggests an alternative model to the most popular clock-based model of mental time-keeping. According to a press release:
- "For decades, scientists have believed that the brain possesses an internal clock that allows it to keep track of time. Now a UCLA study in the Feb. 1 edition of Neuron proposes a new model in which a series of physical changes to the brain’s cells helps the organ to monitor the passage of time.
- "The value of this research lies in understanding how the brain works," said Dean Buonomano, associate professor of neurobiology and psychiatry at the David Geffen School of Medicine at UCLA and a member of the university’s Brain Research Institute. "Many complex human behaviors -- from understanding speech to playing catch to performing music -- rely on the brain’s ability to accurately tell time. Yet no one knows how the brain does it."
- The most popular theory assumes that a clock-like mechanism – which generates and counts regular fixed movements -- underlies timing in the brain. In contrast, Buonomano suggests a physical model that operates without using a clock. He offers an analogy to explain how it works."
I'm headed off to try secure the original article in Neuron and hope to post more detailed information soon. Stay tunned.
